On mainline I'm getting a bootstrap failure building in the libjava directory on sparc-sun-solaris2.10:
Undefined first referenced symbol in file GC_get_thread_stack_base ./.libs/libgcj.so ld: fatal: Symbol referencing errors. No output written to .libs/jv-convert collect2: ld returned 1 exit status make[3]: *** [jv-convert] Error 1 I most recently was able to get a successful bootstrap on Aug 18th: http://gcc.gnu.org/ml/gcc-testresults/2006-08/msg00798.html It was probably triggered by this change because that's where GC_get_thread_stack_base was introduced: 2006-08-21 Bryce McKinlay <[EMAIL PROTECTED]> PR libgcj/13212: * configure.ac: Check for pthread_getattr_np().
