these are no actual changes.
The MSVC compiler comes with a batch file (vcvars32.bat) which you can run
and set some environment variables.
These contain some definitions about the system path, include and library
paths that you need for the correct operation of the command-line compiler.
Normally, there's an entry in the Windows start menu somewhere which is
called "Visual Studio .NET 2003 Command Prompt" and open a console and runs
the mentioned batch file for you.

Clearly, here it should be gensym("float") instead of &s_float... i can
hardly image that this doesn't help. Could you send me the full error
