Oki dokey... How do one go about to fix problems that seems to originate
with the system header files?

When I built rpm, it started to complain about:

----- s n i p ----
gcc -I/home/turbo/src/Build/rpm-2.5.1 -I/home/turbo/src/Build/rpm-2.5.1 -g -O2
-I/usr/local/include -DHAVE_CONFIG_H -I/home/turbo/src/Build/rpm-2.5.1/lib -I/home/turbo/src/Build/rpm-2.5.1/misc   -c files.c -o files.o

----- s n i p ----

And a easy fix for this, was to insert:

----- s n i p ----
/* Added by TURBO. Should'nt be here but... */
#ifndef size_t
# define size_t unsigned int
#endif
----- s n i p ----

Into the file '/usr/include/glob.h'... But this is ovisly not the correct
way, but since this is my first port... It shouldn't break anything though,
since the ifndef...

That's what the progs where doing (first few lines of 'build/files.c'):

----- s n i p -----
#include "config.h"
#ifdef HAVE_GLOB_H
#  include <glob.h>
#else
#  include "misc-glob.h"
#endif
----- s n i p -----

I'll try to add

#ifndef _SYS_SEM_H
#  include <sys/sem.h>
#endif

just before the ifdef HAVE_GLOB_H...
