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.
