When I google "gcc error: calling fdopen: Bad file descriptor" it
seems to be some sort of gcc bug with precompiled headers. The gcc I
use in Linux doesn't have that problem.
I see what happened though; I wanted to include some code to hack
wx/grid.h so wxLua could access some private members which I think
really should be public, but in order to do so I had to duplicate some
#includes before the generated code. In any case, what I did may be a
little hackish, but it is valid as all these headers have include
guards. Could you just rem out the second line of:
#include "wx/wxprec.h"
and it should work. I'll look into somehow fixing it for your version of gcc.

Humm... I do see this in the configure script:
# NB: to avoid getting "-g -02" automatically added to C*FLAGS we need
# to explicitely initialize CFLAGS and CXXFLAGS to empty
CFLAGS=
CXXFLAGS=
I don't know where it came from, but maybe that's clearing it. In the
worst case you can simply stick your settings into these lines of
configure itself. I can't test this right now, but I'll try to see why
this was done.
