I asked if the FSF ever planned on porting gcc to MS-DOS (I wanted to use it to write a 32-bit operating system for PCs), and he said it couldn't be done because gcc was too big and MS-DOS was a 16-bit operating system. Challenge in hand, I began.
The first gcc I built was 1.35, which I built on an ISC Unix system running on a 386/16. I wrote custom replacements for the system calls, linked with ISC's libc.a, write a custom program to turn the resulting binary into a 32-bit EXE that Phar Lap's extender could use, and had the first gcc that ran on MS-DOS."
