That's interesting. Glibc 2.17 and GCC 4.8.0 here. Yet I've built 
alsa-lib without any problems. It looks that stdlib.h pulls sys/types.h 
include. But from what I've seen, it appears to rely on some definition, 
which probably the package that failed for you didn't had defined.

#if defined __USE_SVID || defined __USE_XOPEN_EXTENDED || defined __USE_BSD
# include <sys/types.h>	/* we need int32_t... */

At lines 313 and 314 of /usr/include/stdlib.h
