I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

Trouble compiling code - 'warn_unused_result' attribute directive ignored

Any ideas what is going on here? I've tried an assortment of GCC versions and switches, but no luck just yet. Am trying to compile Compress-Raw-Bzip2-2.019 using "perl Makefile.PL ; make".

gcc -c -I. -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gd +bm -DVERSION=\"2.019\" -DXS_VERSION=\"2.019\" -fPIC "-I/pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib +/5.8.9/x86_64-linux/CORE" -Wall -Wno-comment -DBZ_NO_STDIO -DUSE_PPPORT_H blocksort.c gcc -c -I. -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gd +bm -DVERSION=\"2.019\" -DXS_VERSION=\"2.019\" -fPIC "-I/pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib +/5.8.9/x86_64-linux/CORE" -Wall -Wno-comment -DBZ_NO_STDIO -DUSE_PPPORT_H huffman.c gcc -c -I. -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gd +bm -DVERSION=\"2.019\" -DXS_VERSION=\"2.019\" -fPIC "-I/pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib +/5.8.9/x86_64-linux/CORE" -Wall -Wno-comment -DBZ_NO_STDIO -DUSE_PPPORT_H crctable.c gcc -c -I. -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gd +bm -DVERSION=\"2.019\" -DXS_VERSION=\"2.019\" -fPIC "-I/pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib +/5.8.9/x86_64-linux/CORE" -Wall -Wno-comment -DBZ_NO_STDIO -DUSE_PPPORT_H randtable.c gcc -c -I. -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gd +bm -DVERSION=\"2.019\" -DXS_VERSION=\"2.019\" -fPIC "-I/pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib +/5.8.9/x86_64-linux/CORE" -Wall -Wno-comment -DBZ_NO_STDIO -DUSE_PPPORT_H compress.c gcc -c -I. -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gd +bm -DVERSION=\"2.019\" -DXS_VERSION=\"2.019\" -fPIC "-I/pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib +/5.8.9/x86_64-linux/CORE" -Wall -Wno-comment -DBZ_NO_STDIO -DUSE_PPPORT_H decompress.c gcc -c -I. -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gd +bm -DVERSION=\"2.019\" -DXS_VERSION=\"2.019\" -fPIC "-I/pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib +/5.8.9/x86_64-linux/CORE" -Wall -Wno-comment -DBZ_NO_STDIO -DUSE_PPPORT_H bzlib.c gcc -c -I. -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gd +bm -DVERSION=\"2.019\" -DXS_VERSION=\"2.019\" -fPIC "-I/pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib +/5.8.9/x86_64-linux/CORE" -Wall -Wno-comment -DBZ_NO_STDIO -DUSE_PPPORT_H Bzip2.c In file included from /pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib/5.8.9/x86_64-linux/CORE/perl.h:4561, from Bzip2.xs:14: /pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib/5.8.9/x86_64-linux/CORE/proto.h:31: warning: `warn_unused_ +result' attribute directive ignored /pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib/5.8.9/x86_64-linux/CORE/proto.h:42: warning: `warn_unused_ +result' attribute directive ignored /pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib/5.8.9/x86_64-linux/CORE/proto.h:46: warning: `warn_unused_ +result' attribute directive ignored /pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib/5.8.9/x86_64-linux/CORE/proto.h:50: warning: `warn_unused_ +result' attribute directive ignored /pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib/5.8.9/x86_64-linux/CORE/proto.h:60: warning: `warn_unused_ +result' attribute directive ignored In file included from /pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib/5.8.9/x86_64-linux/CORE/perl.h:4561, from Bzip2.xs:14: /pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib/5.8.9/x86_64-linux/CORE/proto.h:72: warning: `warn_unused_ +result' attribute directive ignored ... several pages more of lines similar to the one above ... /pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib/5.8.9/x86_64-linux/CORE/proto.h:2388: warning: `warn_unuse +d_result' attribute directive ignored Running Mkbootstrap for Compress::Raw::Bzip2 () chmod 644 Bzip2.bs rm -f blib/arch/auto/Compress/Raw/Bzip2/Bzip2.so gcc -shared -O2 -L/pkg/perl-/5.8.9-FAM/x86_64-linux2.6/lib blocksort.o huffman.o crctable.o randta +ble.o compress.o decompress.o bzlib.o Bzip2.o -o blib/arch/auto/Compress/Raw/Bzip2/Bzip2.so + \ \ chmod 755 blib/arch/auto/Compress/Raw/Bzip2/Bzip2.so cp Bzip2.bs blib/arch/auto/Compress/Raw/Bzip2/Bzip2.bs chmod 644 blib/arch/auto/Compress/Raw/Bzip2/Bzip2.bs Manifying blib/man3/Compress::Raw::Bzip2.3

If I 'make test' this, it barfs and fails almost all tests and complains of barewords in the .t files. Is this module any good? As best I can tell from reading the Perl code in the test, these ARE barewords in the .t files.
