I am planning on compiling a few libraries for use with the windows 
installer of Ruby & also apache (eRuby & mod_ruby).

I don't have VC++, so I was planning on using either mingw, mingw cross 
compiler for using cygwin or borland.

I was wondering if there was any tips / pointers to prevent any binary 
incompatabilities? Should it work, or will there be issues or things to 
be aware of?
