as I went through all this configure.in stuff recently,
I noticed that there is the AC_TYPE_SIZE_T, which we don't use.
since I just do not know what side effects -U__GNUG__ might have,
this seems to be more appropriate.
  ./ConfigureMe make --enable-ansi --enable-crm
still works for me.

cvs ci soonish,
unless this macro is not available
in some of the older automake versions ?
