Yes, ftver.rc certainly needs to include windows.h.  But I'm not
cross-compiling.  I'm doing a plain old native Linux build.  That tool
(windres) just happens to exist in /usr/bin.

The current test in builds/freetype.mk is (in pseudocode):

if (the configure script found "rc" or "windres")
    compile ftver.rc

Should it be something more like:

if (the build target is a Windows DLL)
    compile ftver.rc

I'm not sure how to test for that in the Makefile, but there's presumably
some way to do it (?)

I can work around the issue -- thanks for the "make RC=''" suggestion;
that's even simpler than my current workaround.  But I wonder if this
problem may bite someone else in the future.
