building GCC for pSOS on coff-i386

Hello,

I'd like to build a version of GCC 2.95.2 for the pSOS RTOS.  I can build a
basic GCC, but when I get to the 64bit math stuff (like division), the build
fails (can't build the emulation libraries because it lacks some headers.)

Question: Should I use pSOS's headers or should I use newlib's?  I don't
have the expertise to know what nuances there are.  I'd also like to replace
parts of the stdlib of pSOS with newlib implementations.

I would love to know if anyone has done this before and has the exact recipe
or has some tips.

thanks,
greg
