You can redirect stderr to a file with an obscure go32 option listed in
the FAQ somewhere, but it has a side effect: once in a while the error
messages thus redirected end up in the .a files and other files generated
along the compile, assemble, link chain! These of course completely mess
up compilation. Obviously, for its inner workings cc1 or some such
redirects stderr while compiling temporary .a files, which seems
rather stupid to me...they must have their reasons, obscure though these
are. 
As a result this redirection is not that great, and I know of no
alternative that works perfectly. This is one of the compiler's
downsides... maybe V2 has a fix for this.
