I don't understand this?
The current define is pre-existing
#ifdef _GTHREAD_USE_MUTEX_INIT_FUNC
# undef __GTHREAD_MUTEX_INIT
# define __GTHREAD_MUTEX_INIT_FUNCTION __gthread_mutex_init_function
#endif
I suppose it simply forgets to undef __GTHREAD_MUTEX_INIT_FUNCTION like
the _GTHREAD_USE_RECURSIVE_MUTEX_INIT_FUNC does.
I have no access to the weird platforms (but asked for help three month ago
and again a week ago).
Please open new bugs for issues you spot.
Btw, the gthr-posix.h path with _GTHREAD_USE_MUTEX_INIT_FUNC could have
never worked as there was no __gthread_mutex_init_function available
in gthr-posix.h. Or how was that supposed to work?
