I tried to get in touch with Mike and could not. Thus, I am posting
some C header files. I hope this is ok. I won't do it again. To Michael
Schwartz, please direct your G++ concerns to 'gnu.g++' and gnu.g++.bug'.

I made G++ and GCC working for Sun3/50 with f68881.  But I had to make
changes to the original code.  First, you ought to have patched code
to be 1.32.  Second, replace following files with the ones you have.
Also, you ought to keep track of what goes on with GNU software by
reading 'gnu.g++' and 'gnu.g++.bug'.  I hope you can get a working
compiler.
