Neither was I. Here's a brief summary for the list:

I'd like to know how you're supporting other compilers.

I'm sort of supporting borland and comeau for my main project
(although borland's so out of date that I've given up on using it
with modern C++).

For borland, years ago I wrote wrappers that sound just like cccl.
Maybe I should publish them.

For comeau, I've gotten sort of stuck. The thorniest problem is
that the msw 'como' driver seems to be calling system() in a way
that requires $(ComSpec) to point to an ms shell like CMD.EXE .
My notes say:

http://savannah.nongnu.org/cgi-bin/viewcvs/*checkout*/lmi/lmi/como_4_3_3.make?rev=1.5

# Comeau C++ for msw expects its bin/ directory to be on the path and
# the environment to contain a path to gcc. Furthermore, it expects
# to invoke msw subshells. However, we prefer *nix shells and want to
# put nothing compiler specific in the environment.

and go on to explain how I concluded that something like
  sh -c "ComSpec=C:\\\\WINDOWS\\\\SYSTEM32\\\\CMD.EXE; $(MAKE) -f makefile"
is the least yicky workaround. But it's still yicky, and I'd
very much like to know if you've found something better.

I fear I'm veering off topic for this list: these quirks are
probably very specific to Comeau C++. If this isn't the place,
I'd welcome your thoughts in email or on my list here:
  http://lists.nongnu.org/mailman/listinfo/lmi
I did bring this up with Comeau, but it's not something many
of their customers are interested in.
