Is it safe for me to add -I/usr/include/mingw32 to my compile options, or is there a more appropriate way to pick up this header?

It may be OK to do this, but it will be plain luck if it works in this 
case.  Mingw32 stands for the Mingw initiative, that seeks to provide 
a compiler toolset to produce executables that don't rely on cygwin1.dll.
See www.mingw.org for more details.  This directory exists in Cygwin because
the compiler delivered with Cygwin supports cross-compiling to Mingw.  To
invoke this cross compiler, use the -mno-cygwin flag.  If you do so, you 
should find that tchar.h is found, since the compiler will look at this 
path for cross compiling purposes.  You must make sure that you don't need
the POSIX functions only available in Cygwin though if you enable this flag,
since you can't have both Cygwin and Mingw together.  That's why I said 
initially that you can try doing what you describe, but if it doesn't work
or causes problems, you're on your own!;-)
