      Description

      I configured MariaDB with --with-debug=full, but I still get it building with "-O2", for example:

      gcc -DHAVE_CONFIG_H -I. -I../include -I../include -I../include -g -g -O2 -D_P1003_1B_VISIBLE -DSIGNAL_WITH_VIO_CLOSE -DSIGNALS_DONT_BREAK_READ -DIGNORE_SIGHUP_SIGQUIT -DDONT_DECLARE_CXA_PURE_VIRTUAL -MT strxmov.o -MD -MP -MF .deps/strxmov.Tpo -c -o strxmov.o strxmov.c

      It looks like AC_PROG_LIBTOOL sets:

      CFLAGS = -g -O2
      CXXFLAGS = -g -O2

      This is the same with autoconf 2.63 on Mac and autoconf 2.59 on Linux.

      MySQL 5.1.46 configure has the same problem.

      Here is a quick patch which fixes the problem:
