On MacOS, gcc is a symlink for clang. Patch gets rid of the warnings produced by clang, when it is set as HOSTCC, and fixes voicetools compilation on MacOS when calling make voicetools from the simulator directory. lua rb_defines_helper: format specifies type 'int' but the argument has type 'long' codecs: opus / speex (LOGF): format '%ld' expects argument of type 'long int', but argument 7 has type 'off_t' gigabeat: variable 'size' set but not used rdf2binary: a function declaration without a prototype is deprecated in all versions of C rbspeexdec: passing 'unsigned char *' to parameter of type 'char *' converts between pointers to integer types where one is of the unique plain 'char' type and the other is not hmac-sha1.c defining a type within 'offsetof' is a Clang extension Change-Id: I90539906698868f9589650585d865aee9f7e8539
