alloca cannot be a function. #define it to the gcc builtin if possible gcc makes this mapping by default anyway, but it will be disabled by -fno-builtin (and presumably by -std=c99 or similar). for the main program the error will be reported by the linker, and the issue can easily be fixed, but for dynamic-loaded so files, the error cannot be detected until dlopen time, at which point it has become very obscure. 2012-04-09 23:06:58 +04:00			`#define alloca __builtin_alloca`
