  Hi,

when i try to compile grub 1.98 on MacOSX i have this error:

gcc-4.2 -Ignulib -I./gnulib -I/opt/local/include -I. -I./include 
-I./gnulib -I./include -Wall -W -DGRUB_LIBDIR=\"/opt/local/lib/`echo 
grub/i386-pc | sed 's,x,x,'`\" -DLOCALEDIR=\"\" -DGRUB_MACHINE_PCBIOS=1 
-DAPPLE_CC=1 -fnested-functions -DGRUB_UTIL=1 -Wno-undef 
-Wno-sign-compare -Wno-unused -D_GL_UNUSED="__attribute__ ((unused))" 
-I./gnulib -DGRUB_FILE=\"gnulib/getdelim.c\" -MD -c -o 
grub_script_check-gnulib_getdelim.o gnulib/getdelim.c
gnulib/getdelim.c:59: error: expected '=', ',', ';', 'asm' or 
'__attribute__' before 'getdelim'
make: *** [grub_script_check-gnulib_getdelim.o] Error 1

The problem is that the ssize_t type is not defined. We need to add 
#include <unistd.h> on MacOSX like i do on my commit (r2175).
But i know that we can't modify getdelim.c directly because is it imported.
So if someone have an idea to solve this problem on OSX......

Regards,
Yves Blusseau

We should import the ssize_t module from gnulib, which adds a configure
macro for this.  The way grub uses gnulib is a bit odd, though, so it's
not something I'd feel comfortable with just fixing; it needs somebody
more familiar with it.  After we switch to automake (a prerequisite),
could we switch to using gnulib-tool for the gnulib import as well, so
that this becomes a bit more standard?
