Oswald Buddenhagen 98c1d516b7 alloca: detect whether alloca.h exists ... We can't depend on QT_HAS_INCLUDE for such an important functionality in QtQml, so detect at configure time. alloca() is not a POSIX function (it apparently first appeared in Version 32V AT&T UNIX), so the actual header that defines it varies from system to system. Clearly, if alloca.h exists, that's the one, so we try it first. On most other systems that don't define it, it's in stdlib.h. The only exception is Windows, where it's actually defined in malloc.h.
