         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          * (Module): In version 0.99s4, we incorporated the calculation of
           the std error of the proportion of total life expectancy spent in
 2020-02-22  Brouard Nicolas  <brouard@brouard.name>          a specific state Var(e.j/e..) using the formula of Var(X/Y)
           depending only of the variances of X and Y and expectancies.
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy  
         and life table from the data without any state)  2024-04-24  Nicolas Brouard   <brouard@ined.fr>
   
 2019-05-20  Brouard Nicolas  <brouard@brouard.name>          * (Module): This version comes late after having tested
           successfully the praxis C version of Buckhardt.  But Buckardt's
         * version.h: Summary: version 0.99.r19          version was difficult to read and Gegenfurtner's version had a few
           typos which made its results less reliable than Buckhardt's
         * imach.c: Summary: Projection syntax simplified          results.  The most important work consisted in retyping the Brent
         We can now start projections, forward or backward, from the mean date          original PRAXIS program written in Algol W (published with errors,
         of inteviews up to or down to a number of years of projection:          ommitting the transposition of matrix V before its QR reduction
         prevforecast=1 yearsfproj=15.3 mobil_average=0          from Golub. I used the recent "awe" compiler from Gkynn Webster.
         or          The awe library had errors, for example in arc tangent function
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          which have been fixed.
         or  
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          The main objective was to get identical results with the three
         or          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.

           Also, in order to compare them, the random function had to produce
         * imach.c: Summary: doxygen tex bug          the same sequence for the 3 softwares. The random function used in
           imach corresponds to original Brent's random function written in
 2019-05-16  Brouard Nicolas  <brouard@brouard.name>          Algol W.  Other point, in Algol W, the arrays of dimension n are
           'normal' mathematical arrays starting from 1 to n. But this is a
         * imach.c: Summary: There was some wrong lines added          real issue in C where, by default, arrays are starting from 0 to
           n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
 2019-05-09  Brouard Nicolas  <brouard@brouard.name>          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
         * Makefile, imach.c: *** empty log message ***          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
           shifting the index from original X(I) in Algol W to x[i-1] in C.
         * ChangeLog: Summary: C=          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         * imach.c: Summary: Some updates          the original Algol W arrays. Thus the X(I) is translated in C as
           x[i] which minimizes the errors. The Golub QR algorithm was
         * imach.c: Summary: Before ncovmax          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
         * version.h: *** empty log message ***          much more problematic in C than in Algol W.  Thus Buckhardt code
           seems very safe, but i haven't chosen it for IMaCh because the C
         * imach.c: Summary: 0.99r18 unlimited number of individuals          style is horrible and almost unreadable compared to Gegenfürtner
         The number n which was limited to 20,000 cases is now unlimited, from firstobs to lastobs. If the number is too for the virtual memory, probably an error will occur.          CO code which is very close to Brent's original. Also what makes
           Buckhardt code more difficult to read is, instead of passing the
 2018-12-13  Brouard Nicolas  <brouard@brouard.name>          minimum of parameters in the functions calls, as it is in Algol
           Brent's code or Gegenfürtner's code, the list of parameters is
         * imach.c: Summary: Bug for young ages (<-30) will be in r17          high. For example, the flin function LONG REAL PROCEDURE FLIN
           (LONG REAL VALUE L) has only one parameter in Algol W, the
 2018-12-05  Brouard Nicolas  <brouard@brouard.name>          Gegenfürtner flin function had two parameters: static double
           flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         * Makefile: Summary: 0.99r16          function has 14 parameters which makes the code unreadable and
           useless. Gegenfürtner used a lot of static variables or functions
 2018-05-02  Brouard Nicolas  <brouard@brouard.name>          which I tried to minimize. Also in Gegefürtner, array dimensions
           were fixed to N. In my adaptation the flin is static double
         * imach.c: Summary: Some bugs fixed          flin(double l, int j) and the parameter used are global variables.
