#15 Patches for GCC 3.2 (RedHat 8.0)

[Geoffrey T. Dairiki]

With (at least my) GCC 3.2 filebuf's can no longer be
created from FILE*'s or fd's. Libc++ does however
provide and extension class to handle that case.
Patches are attached below.

Instructions:
1. Apply prcs-1.3.2-gcc3.2-conf.patch to configure.in
2. Replace prcs-1.3gcc3.diffs with the one attached below
3. Rerun autoheader and autoconf
4. configure and make as usual

(The only changes in prcs-1.3gcc3.diffs are for:
src/rebuild.cc
src/prcserror.cc
src/include/prcs.h
)
