Tkinter: return value of mp_init() should not be ignored #106350
Description
An mp_int structure is usable only if mp_init() returns MP_OKAY; mp_init() may return MP_MEM if it fails to allocate memory (see https://github.com/libtom/libtommath/blob/v1.2.0/bn_mp_init.c#L12).
mp_init() must be checked to avoid a warning when compiling against standalone libtommath headers (rather than Tcl-bundled libtommath):
./Modules/_tkinter.c:908:5: warning: ignoring return value of function declared with 'warn_unused_result' attribute [-Wunused-result]
mp_init(&bigValue);
