Very interesting. I just tried that on the meaty configure script of net-snmp. $ gcc -v Reading specs from /data2/nm/sw/gcc341/bin/../lib/gcc/i686-pc-linux-gnu/3.4.1/specs Configured with: ../gcc-3.4.1/configure --prefix=/home/nm/sw/gcc341 --enable-languages=c --with-system-zlib Thread model: posix gcc version 3.4.1 Notable misbehavior: configure:10244: checking for asin in -lm configure:10275: gcc -std=c99 -pedantic-errors -Werror -o conftest -g -O2 -Dlinux conftest.c -lm >&5 configure:10296: warning: conflicting types for built-in function 'asin' The `conflicting types for built-in function FOO' warning also arises for strchr, memcpy, memmove, vsnprintf, and snprintf. configure:18609: checking for working memcmp configure:18658: gcc -std=c99 -pedantic-errors -Werror -o conftest -g -O2 -Dlinux conftest.c -lcrypto -lelf >&5 configure: In function `main': configure:18743: warning: overflow in implicit constant conversion configure:18743: warning: overflow in implicit constant conversion configure:18744: error: implicit declaration of function `memcmp' configure:18745: error: implicit declaration of function `exit' configure:18758: error: implicit declaration of function `strcpy' configure:18661: $? = 1 configure: program exited with status 1 configure: failed program was: <snipped> configure:18680: result: no I posted the full log at http://www.cs.caltech.edu/~noah/net-snmp-config-log.gz for the time being. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
