You're right, of course. I should have looked closer. Testing and
comparison with pthread results found two other bugs, one of which I
could already fix in gthr-solaris.h. I've tried to debug the other
(objc) testcase, but gdb 6.6 cannot fully handle it, and I couldn't yet
get a gdb 7.0 to debug a 64-bit binary.
Given that this is a bootstrap failure, I'll submit and install the fix
now and check the remainder later.

The #c4 patch looks wrong, instead of that you should IMHO just not use UNUSED
macro on __gthread_mutex_destroy argument. It is perfectly fine on
__gthread_key_delete.

True, but why not omit any --{enable, disable}-threads option and use
the default?

Sure: the default should be fine unless you have specific reasons to
prefer UI threads instead. This has nothing to do with OpenSolaris in
any way, but is true for any recent Solaris 2 release.

Is it better to let configure guess about thread model on OpenSolaris x86 32bit
build >= snv_126?

Why are you building with --enable-threads=solaris in the first place?
Just omit --enable-threads (defaulting to posix); the implementation of
both on Solaris 2 is the same, anyway. It is beyond me why anyone would
want to program to the old UI Threads interface.
That said, I'm testing the obvious fix:
Index: gcc/gthr-solaris.h
===================================================================
--- gcc/gthr-solaris.h (revision 154216)
+++ gcc/gthr-solaris.h (working copy)
@@ -37,7 +37,7 @@
#include <errno.h>
#ifdef __cplusplus
-#define UNUSED(x)
+#define UNUSED(x) x
#else
#define UNUSED(x) x __attribute__((unused))
#endif
I've now idea what other problems with --enable-threads=solaris might
exist, though. This isn't regularly tested.

------- Comment #2 from paolo dot carlini at oracle dot com 2009-10-23 18:14 -------
Let's CC Rainer. IMHO something is broken in gthr-solaris.h, I see:
#ifdef __cplusplus
#define UNUSED(x)
#else
#define UNUSED(x) x __attribute__((unused))
#endif
...
static inline int
__gthread_mutex_destroy (__gthread_mutex_t * UNUSED(__mutex))
{
if (__gthread_active_p ())
return __gthrw_(mutex_destroy) (__mutex);
else
return 0;
}
which cannot be Ok when __cplusplus is defined. Not a libstdc++ proper issue.
