This is my haphazzard GCC 1.40 port to Windows NT December 1991 pre-relase.
I've included a floppy image, along with the zip file, containing binaries of GCC/GAS along with zips of the source code.
For some reason the C pre-processor hangs if there is more than one include file, So I use the Microsoft C/386 compiler to pre-process. Note that the binary formats changed an incredible amount and phoon.exe will *NOT* run on any modern machine.
This is strictly for 1991 Windows NT, with floating point support.
