Greetings.

The package refuses to build —even in a clean chroot—, stating:
[code]
signature.cpp:49:76: error: narrowing conversion of '181' from 'int' to 'char' inside { } [-Wnarrowing]
0xb5, 0x8b, 0x06, 0x66, 0x82, 0x6c, 0x2b, 0xac, 0x00 };
^
signature.cpp:49:76: error: narrowing conversion of '174' from 'int' to 'char' inside { } [-Wnarrowing]
signature.cpp:49:76: error: narrowing conversion of '181' from 'int' to 'char' inside { } [-Wnarrowing]
signature.cpp:49:76: error: narrowing conversion of '139' from 'int' to 'char' inside { } [-Wnarrowing]
signature.cpp:49:76: error: narrowing conversion of '130' from 'int' to 'char' inside { } [-Wnarrowing]
signature.cpp:49:76: error: narrowing conversion of '172' from 'int' to 'char' inside { } [-Wnarrowing]
[/code]

As a result, aur/lib32-musicbrainz won't build either, with the same output.

I suspect it has to do with gcc, but I cannot know, alas I'm not a programmer. I attach the full log, though.

Thank you.
