Since this change I am seeing the following in my night GCC build and test logs on FreeBSD systems: gmake[2]: autogen: Command not found gmake[2]: *** [Makefile:176: check] Error 127 gmake[1]: *** [Makefile:3759: check-fixincludes] Error 2 /scratch/tmp/gerald/GCC-HEAD/libbacktrace/ztest.c: In function 'test_large': /scratch/tmp/gerald/GCC-HEAD/libbacktrace/ztest.c:384:41: warning: passing argument 2 of 'uncompress' from incompatible pointer type [-Wincompatible-pointer-types] r = uncompress (uncompressed_buf, &uncompressed_bufsize, ^~~~~~~~~~~~~~~~~~~~~ In file included from /scratch/tmp/gerald/GCC-HEAD/libbacktrace/ztest.c:43:0: /usr/include/zlib.h:1265:21: note: expected 'uLongf * {aka long unsigned int *}' but argument is of type 'size_t * {aka unsigned int *}' ZEXTERN int ZEXPORT uncompress OF((Bytef *dest, uLongf *destLen, ^~~~~~~~~~ /scratch/tmp/gerald/GCC-HEAD/libbacktrace/ztest.c: In function 'test_large': /scratch/tmp/gerald/GCC-HEAD/libbacktrace/ztest.c:384:41: warning: passing argument 2 of 'uncompress' from incompatible pointer type [-Wincompatible-pointer-types] r = uncompress (uncompressed_buf, &uncompressed_bufsize, ^~~~~~~~~~~~~~~~~~~~~ In file included from /scratch/tmp/gerald/GCC-HEAD/libbacktrace/ztest.c:43:0: /usr/include/zlib.h:1265:21: note: expected 'uLongf * {aka long unsigned int *}' but argument is of type 'size_t * {aka unsigned int *}' ZEXTERN int ZEXPORT uncompress OF((Bytef *dest, uLongf *destLen, ^~~~~~~~~~ gmake[4]: *** [Makefile:306: check-DEJAGNU] Error 1 gmake[3]: *** [Makefile:350: check-am] Error 2 gmake[2]: *** [Makefile:904: check-recursive] Error 1 gmake[1]: *** [Makefile:22343: check-target-libgomp] Error 2 Fatal error 'mutex is on list' at line 272 in file /usr/src/lib/libthr/thread/thr_mutex.c (errno = 0) Fatal error 'mutex is on list' at line 272 in file /usr/src/lib/libthr/thread/thr_mutex.c (errno = 0) gmake: *** [Makefile:2286: do-check] Error 2 Gerald
