I did that for years, on many Unices, and it works very well, except
for one problem.

Software with poxious forms of autoconfiguration will poke around your
system and select one or other compiler at whim - or, in many cases,
a dysfunctional combination of all of them.  Unfortunately, MOST
modern, complex software does at least some of that and you have to
reverse engineer its autoconfiguration to hack around the bugs.  That
can be anywhere from simple to almost impossible.

The only solution to that problem involves the authors of the software,
a dark alley and a blunt instrument.
