I suppose it's stupid to lose backwards compability for diagnostics and the pragmas should be moved out of the function again.

With GNU GCC 4.5.3:

udisksclient.c: In function 'udisks_client_get_id_for_display':
udisksclient.c:2219:9: error: #pragma GCC diagnostic not allowed inside functions
udisksclient.c:2220:9: error: #pragma GCC diagnostic not allowed inside functions
udisksclient.c:2222:17: warning: format not a string literal, argument types not checked [-Wformat-nonliteral]
udisksclient.c:2224:17: warning: format not a string literal, argument types not checked [-Wformat-nonliteral]
udisksclient.c:2226:9: error: #pragma GCC diagnostic not allowed inside functions
udisks-generated.c: In function '_udisks_drive_emit_changed':

I can verify udisks-1.99.0 builds OK with gcc-4.6 and gcc-4.7, but not with gcc-4.5 or older.
