windef.h redefined BOOL at line 125 (__OBJC__ not defined).
The problem occurs when compiling:
/../gcc-3.0.1/libobjc/thr-objc.c
The expansion of the includes places 'objc.h' before 'windef.h' and both contain a definition of BOOL. Comments in windef.h (and windows.h) indicate that this is a known problem with no solution. I would like to help on this if I can. Is there a resource that I can read that describes the problem in more detail?
There is a cute trick used in 'gthr-win32.h' which may be relevant, to wit:
<read in includes>
#define BOOL
#undef BOOL
<read in more includes>
which if I understand correctly, since the macro BOOL takes precedence during parsing over the typedef BOOL allows the typedef to be masked.

configure --enable-threads=win32
make bootstrap
make install

comment out the definition of BOOL in windef.h
