        For godssake, this did not really affect the make-process. Maybe

        I could even do without "make depend" anyways, never tried though.

        Still I have not the slightest idea why this happened.
     
     
 This is obnoxious, but not really an error.  my personal opinion is that this
is a problem with the C library or make depend.

 On my system in fact (running glibc 2.2), I had to modify one of the files in
/usr/include because it had a line like:
#define stderr stderr
which makedepend barf's on - I wouldn't really be concerned with that, except
that data it then dumps into the Makefiles is bad.

 Fixed (or should be).  I thought I had added that file to the cvs repository,
but apparantly that commit didn't take or I forgot the cvs add.

          Easy to fix for me, but not so easy to make it work on every OS...
     
     
 I think I have a better check in the configure.in - when checking for libdes,
it will also check to see that des_crypt is in it.

 Unfortunately, none of the systems I use (redhat linux or solaris) have/use
libdes by default, so this is only something I and attempt to adjust based on
feedback and hope I get it right.

 Found the bug for that - will check in a change shortly (sometime this
evening).  The makefile.in had some ($XX_...) instead of $(XX_...) entries in
it.
