similar to: [PATCH] Disable -Wunsafe-loop-optimizations

Add some warnings. Well, the first patch is a miscellaneous change, but patches 2-5 add some warnings. Rich.

These patches first make src/ warning free, and then turn on the strict warning options. 75 0001-build-suppress-an-ignored-write-return-value-warning.patch 38 0002-build-suppress-an-ignored-dup-return-value-warning.patch 27 0003-generator.ml-suppress-signed-unsigned-compare-warnin.patch 48 0004-build-don-t-perform-arithmetic-on-void-pointers.patch 30

Older GCC versions (e.g. < 4.9) may complain about inline functions that cannot be inlined (growing the generated code). It is not really a problem for us, so just suppress again the warning.

I'm quite sure that's the culprit. Add -O3 to your

Counteract incorrect use of the "deprecated" attribute in ffmpeg headers. In particular, struct AVPaletteControl is deprecated, but it's used in a non-deprecated struct AVCodecContext (as found in Fedora's ffmpeg-devel-0.4.9-0.8.20070530.fc7.x86_64). Define attribute_deprecated to an empty string until broken version of ffmpeg are too obsolete to support. Use appropriate

The warnings in daemon were aggravating and risky for development (too easy to miss new ones) so I spent some time last week and today working on removing them. The first patch gets us down to almost no warnings with the original -Wall setting. That was by far the hardest part. Once I'd done that, I enabled nearly all of gcc's warnings via gnulib's warnings and manywarnings modules

Hi all! Yesterday I upgraded to FreeBSD 10.0-RC1 through freebsd-update. Everything seemed fine until I decided to upgrade my ports today. There was a new version of pkg which built fine up until the linking: ===> Building for pkg-1.2.3 --- all --- ===> libpkg (all) --- objwarn --- --- libpkg.so.1 --- --- objwarn --- Warning: Object directory not changed from original

FWIW, configure is already checking to see whether the compiler is gcc or not. There's an if clause in the configure scripts for ogg, vorbis, theora, and other of our packages that uses this to add

Currently we have RH7.3 with compiler gcc 2.96.x My mission, should I choose to accept it, involves moving our embedded application to CentOS 4.1 with gcc 3.x Problem is that about 1/2 million lines of code that gcc 2.96 accepts gives fatal fits to the gcc 3.x compiler from CentOS 4.1 I don't know how many fatal fits, as some disguise others etc. "Can't find register to

Hello, Upon compiling the flac tree today, after many successful compilations over the last few weeks, a new error is appearing before compilation bails out. This is a cross-compilation using gcc-5.3.0 running on GNU/Linux, with the objects being built for a mingw-w64-x86_64 host. Among other things, the compiler is looking for windows_unicode_filenames.h but it isn't there. Also, I'm
