I have modified gcc to accept a new switch called: -posix. This will
cause '-D_POSIX_SOURCE' to be passed to the preprocessor and ld
to use the Posix startup files and link with -lcposix before -lc. This
seems to work fine for Interactive (386/ix) 2.2 OS.

I'm wondering what other systems define in their OS headers for Posix
compliance. Is _POSIX_SOURCE a standard, or something unique to
Interactive? Do other Posix systems have separate startup files and
C libraries? Is it just too early to try and standardize Posix and gcc?

In any case, the diffs are pretty small so here they are:
