[Dev-C++] WxWindows & Dev-c++ ?

[Pieter T. <pie...@pa...>]

I've installed Dev-c++ 4.01 together with the Cygwin compiler
I have successfully build wxMSW 2.2.7, and have been able to compile the
wxWindows template program (using cygwin, called from within dev-c++) that
comes in the wxWindows 2.2.7 for MingW package.

What I don't understand: the template explicitly includes <windows.h>.

When I leave this out, I get lots of compilers errors (parse errors in wx
header files) when compiling from within Dev-C++

Yet when compiling from the command line it works (as it should) without
explicitly specifying windows.h

What am I doing wrong?
Normally there's no need for wx programs to include windows.h ?
