Fastest C++ Compiler?

[Darren Cook <darren@xxxxxxxxxxxxxx>]

Which compiler makes the fastest code? This thread came up a year or so ago,
with people saying either gcc or Watcom if I remember correctly.

I'm using Visual C++ 4.0, and wondered how easy it would be to recompile
just certain files (ie. those that do search and analysis) in gcc, but leave
all the interface-related code (which uses MFC) with visual c++.

Is it possible to link gcc object files using visual C++? I'm thinking I'll
do the development and debugging in visual C++, and then once I've got an
algorithm finished I'll recompile it with gcc.

Does anyone have any advice, or experience doing this?
