When you say remove the #if you mean just the #if statement or all of the
code in the #if statement. As you can tell that is a strange hack for that
compiler and I wish I documented the version.

What gcc are you using? MingW as per these directions or something else and
from where and why?

http://wxlua.sourceforge.net/docs/install.html#C2.4
http://sourceforge.net/projects/mingw/files/Installer/mingw-get-inst/

The mingw-get-inst-20120426<http://sourceforge.net/projects/mingw/files/Installer/mingw-get-inst/mingw-get-inst-20120426/>is
gcc 4.7.0 and I do believe that that #if is needed for that compiler.
