Turns out Borland made Turbo C (a great compiler and IDE for its day)
available for free download from
<http://community.borland.com/article/0,1410,20841,00.html>. And, I was
curious, since there's a lot of nostalgia value for me, and I found that it
works wonderfully in DOSBox, the i386/DOS emulator -- which is available
from Fedora Extras. (So you could even use it on PPC.)

Hmm. They also have Turbo C++ 1.01 available for free -- that dates to 1991.
<http://community.borland.com/article/0,1410,21751,00.html>. This is
probably the one you want, since it also includes a plain C compiler, which
clearly states: "ANSI C!  A 100% implementation of the ANSI C standard".
This means that programs you write *will* compile in both, provided you
don't use anything newer than the original ANSI C (or any nonstandard
extensions from either compiler). (Use the gcc -ansi option.)

DOSBox is also great if you ever need to delve into learning i386 assembly,
because you can't crash your actual machine.
