Header files for building libgcc

[John Hsu <jonhsu@xxxxxxxxxxxxx>]

Hello,

I was wondering what standard header files are used when building libgcc
for the Pro64 compiler. In particular, I'm trying to build tinfo.cc and
I get conflicts with the typeinfo header file, which does not appear to
be in the Pro64 source distribution. I think perhaps the standard
C++ header files I have are outdated, but I don't know what version is
needed.
