Cheapest way to Unix program developement

[Rob Haynes]

I'm looking for the cheapest way to do program development on Unix.  I
plan to buy a 386 PC, put a unix without a development toolkit on it,
get the GNU CC, AS, and LD.  The question is, is that enough to do
program development?  A relevant question is, do the various 386
unix's come with libraries (like libc.a, libtermcap.a, etc.).  If not,
is there enough documentation to do direct system calls?
