egcs-1.1.2 cross compiler problems

[Teemu Torma]

I have tried for the first time to set egcs to work as a cross
compiler to be able to compile sparc-sun-solaris2.5.1 binaries under
sparc-sun-solaris2.7.  This same setup worked out-of-the-box with gcc
2.7.2.3.

The configuration was done as:

../egcs-1.1/configure --target=sparc-sun-solaris2.5.1 --srcdir=../egcs-1.1 --prefix=/usr/gnu --with-cpu=supersparc --enable-version-specific-runtime-libs --enable-shared --with-gnu-as --with-gnu-ld

I encountered two fatal problems with this setup:

1. The generated include/limits.h does include code to #include_next
   the system limits.h (limitx.h and limity.h).  This causes that
   config/sparc/gmon-sol2.c does not even compile because it does not
   get PATH_MAX from limits.h.  

2. When building a cross compiler, libgcc2.c does automatically
   #define inhibit_libc.  At least __eprintf will be missing and
   causing link failures.

After fixing those two things manually, everything seems to be in
working order.
