_API_Mutex_Lock and interrupts

[Jay Monkman]

I just tried updating to the 20020717 snapshot, and am getting funny
problems. I'm not sure but it looks like the source is
_API_Mutex_Lock.


    #define _API_Mutex_Lock( _the_mutex ) \
    do { \
       ISR_Level _level;  \
       _CORE_mutex_Seize( \
       &(_the_mutex)->Mutex, (_the_mutex)->Object.id, TRUE, 0, (_level)); \
    } while (0)

_CORE_mutex_Seize starts with:
    #define _CORE_mutex_Seize( \
        _the_mutex, _id, _wait, _timeout, _level ) \
    do { \
        if ( _CORE_mutex_Seize_interrupt_trylock( _the_mutex, &_level ) )

And _CORE_mutex_Seize_interrupt_trylock makes several calls to
_ISR_Enable.

But, _level never gets initialized as far as I can see. Am I missing
something, or is the code wrong?
