irix 5.3 nits

[Bill Schottstaedt]

I tried to build the snapshot on SGI Irix 5.3, and hit a few problems.
First, inttypes.h and sys/types.h aren't compatible on this system:

/usr/people/bil/test/guile-core-20010820/ make

I reported this earlier to autoconf, and they fixed it in some way:

from autoconf Changelog:

2001-06-23  Akim Demaille  <address@hidden>

        * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
        inttypes.h is missing if it conflicts with sys/types.h, as on IRIX
        5.3.


Next, the ptrdiff_t complaint -- I couldn't immediately see what it's problem 
was, so
I set that flag by hand and:


cc -DHAVE_CONFIG_H -I.. -I./.. -I../libltdl -g -c gc_os_dep.c  -DPIC -o 
gc_os_dep.o
cfe: Warning 753: /usr/include/sys/types.h, line 105: declaration must at least 
declare an identifier, tag, or the  
member of an enumeration
 typedef        unsigned long   int ;
 ^
cfe: Error: gc_os_dep.c, line 1765: redeclaration of 'GC_noop1'; previous 
declaration at line 1753 in file 'gc_os_dep.c'

 ----^
cfe: Error: gc_os_dep.c, line 1765: Incompatible function return type for this

I couldn't find GC_noop1.
