+  Revision 1.101  2004/09/15 10:38:38  brouard
+  Fix on curr_time
+
+  Revision 1.100  2004/07/12 18:29:06  brouard
+  Add version for Mac OS X. Just define UNIX in Makefile
+

+  *** empty log message ***
+
+  Revision 1.98  2004/05/16 15:05:56  brouard
+  New version 0.97 . First attempt to estimate force of mortality
+  directly from the data i.e. without the need of knowing the health
+  state at each age, but using a Gompertz model: log u =a + b*age .
+  This is the basic analysis of mortality and should be done before any
+  other analysis, in order to test if the mortality estimated from the
+  cross-longitudinal survey is different from the mortality estimated
+  from other sources like vital statistic data.
+
+  The same imach parameter file can be used but the option for mle should be -3.
+
+  Agnès, who wrote this part of the code, tried to keep most of the
+  former routines in order to include the new code within the former code.
+
+  The output is very simple: only an estimate of the intercept and of
+  the slope with 95% confident intervals.
+
+  Current limitations:
+  A) Even if you enter covariates, i.e. with the
+  model= V1+V2 equation for example, the programm does only estimate a unique global model without covariates.
+  B) There is no computation of Life Expectancy nor Life Table.
+
+  Revision 1.97  2004/02/20 13:25:42  lievre
+  Version 0.96d. Population forecasting command line is (temporarily)
+  suppressed.
+
+  Revision 1.96  2003/07/15 15:38:55  brouard
+  * imach.c (Repository): Errors in subdirf, 2, 3 while printing tmpout is
+  rewritten within the same printf. Workaround: many printfs.
+
+  Revision 1.95  2003/07/08 07:54:34  brouard
+  * imach.c (Repository):
+  (Repository): Using imachwizard code to output a more meaningful covariance
+  matrix (cov(a12,c31) instead of numbers.
+
+  Revision 1.94  2003/06/27 13:00:02  brouard
+  Just cleaning
+
+  Revision 1.93  2003/06/25 16:33:55  brouard
+  (Module): On windows (cygwin) function asctime_r doesn't
+  exist so I changed back to asctime which exists.
+  (Module): Version 0.96b
+
+  Revision 1.92  2003/06/25 16:30:45  brouard
+  (Module): On windows (cygwin) function asctime_r doesn't
+  exist so I changed back to asctime which exists.
+
+  Revision 1.91  2003/06/25 15:30:29  brouard
+  * imach.c (Repository): Duplicated warning errors corrected.
+  (Repository): Elapsed time after each iteration is now output. It
+  helps to forecast when convergence will be reached. Elapsed time
+  is stamped in powell.  We created a new html file for the graphs
+  concerning matrix of covariance. It has extension -cov.htm.
+
+  Revision 1.90  2003/06/24 12:34:15  brouard
+  (Module): Some bugs corrected for windows. Also, when
+  mle=-1 a template is output in file "or"mypar.txt with the design
+  of the covariance matrix to be input.
+
+  Revision 1.89  2003/06/24 12:30:52  brouard
+  (Module): Some bugs corrected for windows. Also, when
+  mle=-1 a template is output in file "or"mypar.txt with the design
+  of the covariance matrix to be input.
+
+  Revision 1.88  2003/06/23 17:54:56  brouard
+  * imach.c (Repository): Create a sub-directory where all the secondary files are. Only imach, htm, gp and r(imach) are on the main directory. Correct time and other things.
+
+  Revision 1.87  2003/06/18 12:26:01  brouard
+  Version 0.96
+
+  Revision 1.86  2003/06/17 20:04:08  brouard
+  (Module): Change position of html and gnuplot routines and added
+  routine fileappend.
+
+  Revision 1.85  2003/06/17 13:12:43  brouard
+  * imach.c (Repository): Check when date of death was earlier that
+  current date of interview. It may happen when the death was just
+  prior to the death. In this case, dh was negative and likelihood
+  was wrong (infinity). We still send an "Error" but patch by
+  assuming that the date of death was just one stepm after the
+  interview.
+  (Repository): Because some people have very long ID (first column)
+  we changed int to long in num[] and we added a new lvector for
+  memory allocation. But we also truncated to 8 characters (left
+  truncation)
+  (Repository): No more line truncation errors.
+
+  Revision 1.84  2003/06/13 21:44:43  brouard
+  * imach.c (Repository): Replace "freqsummary" at a correct
+  place. It differs from routine "prevalence" which may be called
+  many times. Probs is memory consuming and must be used with
+  parcimony.
+  Version 0.95a3 (should output exactly the same maximization than 0.8a2)
+
+  Revision 1.83  2003/06/10 13:39:11  lievre
