Absolutely.  That's exactly the info I was looking at.  Someone should 
add this to the README.win32 file, btw.

On a positive note, the compiling on windows on latest stable and 
unstable branches has indeed improved.  At least now the .dll and .lib's 
generated carry the compiler version in them.

For what it is worth, it would also be ideal if configure.bat would 
allow out of source builds, like autotools (or would do out of source 
builds by default).  That way you could avoid doing nmake clean each time.
