Better would be a conditional definition in
memalloc/common/current/include/kapi.h. Something like this:

#ifndef CYGPKG_KERNEL
typedef cyg_uint32 cyg_handle_t;
#endif

There are quite a lot of functions with weak attributes scattered
around the sources. Take a look, for example, at hal_spurious_IRQ() in
the ARM architecture HAL. There certainly shouldn't be any compiler
problems in this area, it's platform independent and has been working
for years.
