         * imach.c (Module): Insert of a warning if the delay between two          * imach.c (Repository): Check when date of death was earlier that
         waves is negative.          current date of interview. It may happen when the death was just
           prior to the death. In this case, dh was negative and likelihood
         * imach.c (Module):          was wrong (infinity). We still send an "Error" but patch by
           assuming that the date of death was just one stepm after the
 2003-05-03    <brouard@BROUARD>          interview.
           (Repository): Because some people have very long ID (first column)
         * imach.c: Some cleaning          we changed int to long in num[] and we added a new lvector for
 2003-03-28    <brouard@BROUARD>          memory allocation. But we also truncated to 8 characters (left
           truncation)
         * imach.c (Module): In version up to 0.92 likelihood was computed          (Repository): No more line truncation errors.
         as if date of death was unknown. Death was treated as any other  
         health state: the date of the interview describes the actual state  2003-06-14  Brouard Nicolas  <brouard@homebrou>
         and not the date of a change in health state. The former idea was  
         to consider that at each interview the state was recorded          * imach.c (Repository): Add of a routine likelione (likelihood
         (healthy, disable or death) and IMaCh was corrected; but when we          only once) which prints on a text file
         introduced the exact date of death then we should have modified          (ilk) the contributions to the likelihood for each
         the contribution of an exact death to the likelihood. This new          individual/wave.
         contribution is smaller and very dependent of the step unit  
         stepm. It is no more the probability to die between last interview  2003-06-13  Brouard Nicolas  <brouard@homebrou>
         and month of death but the probability to survive from last  
         interview up to one month before death multiplied by the          * imach.c (Repository): Replace "freqsummary" at a correct
         probability to die within a month. Thanks to Chris          place. It differs from routine "prevalence" which may be called
         Jackson for correcting this bug.  Former versions increased          many times. Probs is memory consuming and must be used with
         mortality artificially. The bad side is that we add another loop          parcimony.
         which slows down the processing. The difference can be up to 10%  
         lower mortality.  2003-06-17    <brouard@BROUARD>
   
 2002-05-30    <brouard@BROUARD>          * timeval.h (Module): Added included file to make use of
           gettimeofday working on win32 with cygwin.
         *  
   2003-05-16  Brouard Nicolas  <brouard@brouard>
         * imach.c (Module): Add correlation matrix of one-step  
         probabilities and covariance matrix          * imach.c (Module): Insert of a warning if the delay between two
           waves is negative.
   
           * imach.c (Module):
