Disclaimer: I don't know what winbase.h is.

If it's provided by the OS or by some installable package
(another followup suggests that it's part of a Perl installation,
in C:\Perl\site\lib\auto\MinGW\include), then modifying it is
unlikely to be the best solution.  It might fix your own build
problem but if your application's source code depends on a change
to some system header it's going to be a real portability problem.

Instead, I'd suggest adding that declaration somewhere in your own
application's source code.

And if that's a missing declaration that *should* be in that header,
consider reporting the problem to the provider of that header file.
There's no winbase.h in the Perl source tree.  Perhaps it's provided
by some third party, likely Strawberry or ActiveState.

    used by contemporary perl.

Did you define that macro *before* the relevant #include
directive(s)?

If you mean you want to see the output of the preprocessor, you can use
"gcc -E".

I'll note again that I don't know what winbase.h is or who
provides it.  I'm making assumptions based on the directory path.
