Hi
On m32c-rtems, we have a build error in C++ because size_t
is 16-bits and pointers are 24 bits. m32c-elf probably does not
enable __GTHREAD support like rtems does. Since this is code
shared across targets, what is the best way to fix this?
My first inclination would be to use uintptr_t for the variable
_M_id but I don't know what other impacts that would have
or where else this needs to be fixed.
../../../../../../gcc/libstdc++-v3/src/c++98/mt_allocator.cc: In
function 'void {anonymous}::_M_destroy_thread_key(void*)':
../../../../../../gcc/libstdc++-v3/src/c++98/mt_allocator.cc:77:51:

size_t _M_id = reinterpret_cast<size_t>(__id);
