FTR, I was building snapshots of what will shortly become GDB 10.1.

Maybe it's worth reporting to [email protected], as a
potential bug.  if the GDB developers have good reasons not to support
this option, they will tell; otherwise I think it's reasonable to
expect it be supported, given the common configuration machinery.

I think the canonical ways of doing this is to set CPPFLAGS when
running 'configure', i.e.

 CPPFLAGS=-I/mingw ./configure ...

Did you try that?
