| Subject: | Unrecognized option `-Wdisabled-optimization' |
For gcc v2.96, `-Wdisabled-optimization' is not a valid compiler option,
and caused 'make' to fail:
gcc -c -D_REENTRANT -D_GNU_SOURCE -DTHREADS_HAVE_PIDS -DDEBUGGING
-fno-strict-aliasing -I/usr/local/include -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm -O2 -g -pipe -march=i386
-mcpu=i686 -DVERSION=\"1.50\" -DXS_VERSION=\"1.50\" -fPIC
"-I/usr/lib/perl5/5.8.0/i386-linux-thread-multi/CORE" -W -Wall
-Wpointer-arith -Wbad-function-cast -Wno-comment -Wno-sign-compare
-Wno-cast-qual -Wdisabled-optimization -Wmissing-noreturn
-Wno-unused-parameter Perl.c
