No, PTHREAD_MUTEX_INITIALIZER is for static initialization only.
Depending on the OS, it's probably an aggregate initializer, and may
look something like "{ 0, SOME_FLAG_HERE, 0 }", so you can imagine
where the syntax error is coming from. This isn't a gcc bug, it's a
bug in the code.
C99 does have a syntax for compound literals that can be used as
structure values, with a slightly different syntax from what you
quote above, but the POSIX spec describing PTHREAD_MUTEX_INITIALIZER
does specifically talk about static initialization, not
initialization or assignment in general. For dynamic initialization,
you should be calling pthread_mutex_init.
(This would've been more appropriate for the gcc-help list.)
