         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          * (Module): This version comes late after having tested
           successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          typos which made its results less reliable than Buckhardt's
           results.  The most important work consisted in retyping the Brent
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          original PRAXIS program written in Algol W (published with errors,
           ommitting the transposition of matrix V before its QR reduction
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          which have been fixed.
         and life table from the data without any state)  
           The main objective was to get identical results with the three
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          versions: (1) Algol W, (2) Buckhardt'C version as well (3)
           Gegenfürtner C versions on the various test functions published by
         * version.h: Summary: version 0.99.r19          Brent in 1973 in Algol W.
   
         * imach.c: Summary: Projection syntax simplified          Also, in order to compare them, the random function had to produce
         We can now start projections, forward or backward, from the mean date          the same sequence for the 3 softwares. The random function used in
         of inteviews up to or down to a number of years of projection:          imach corresponds to original Brent's random function written in
         prevforecast=1 yearsfproj=15.3 mobil_average=0          Algol W.  Other point, in Algol W, the arrays of dimension n are
         or          'normal' mathematical arrays starting from 1 to n. But this is a
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          real issue in C where, by default, arrays are starting from 0 to
         or          n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          seen that authors while trying to mimick original Brent Algol W
         or          code are hesitating by changing either a loop originally from 1 to
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          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.
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         * imach.c: Summary: doxygen tex bug          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
 2019-05-16  Brouard Nicolas  <brouard@ined.fr>          published in Algol with overflow errors which were reproduced in
           Brent's Algol W code. Buckhardt code fixed these errors which are
         * imach.c: Summary: There was some wrong lines added          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
 2019-05-09  Brouard Nicolas  <brouard@ined.fr>          style is horrible and almost unreadable compared to Gegenfürtner
           CO code which is very close to Brent's original. Also what makes
         * Makefile, imach.c: *** empty log message ***          Buckhardt code more difficult to read is, instead of passing the
           minimum of parameters in the functions calls, as it is in Algol
         * ChangeLog: Summary: C=          Brent's code or Gegenfürtner's code, the list of parameters is
           high. For example, the flin function LONG REAL PROCEDURE FLIN
         * imach.c: Summary: Some updates          (LONG REAL VALUE L) has only one parameter in Algol W, the
           Gegenfürtner flin function had two parameters: static double
         * imach.c: Summary: Before ncovmax          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
           function has 14 parameters which makes the code unreadable and
         * version.h: *** empty log message ***          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
         * imach.c: Summary: 0.99r18 unlimited number of individuals          were fixed to N. In my adaptation the flin is static double
         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.          flin(double l, int j) and the parameter used are global variables.
