* ansidecl.h:
(ATTRIBUTE_RESULT_SIZE_1): Define new macro.
(ATTRIBUTE_RESULT_SIZE_2): Likewise.
(ATTRIBUTE_RESULT_SIZE_1_2): Likewise.
* libiberty.h (xmalloc): Add RESULT_SIZE attribute.
(xrealloc): Likewise.
(xcalloc): Likewise.
broke bootstrap on Solaris/x86 and Solaris/SPARC (and probably other 32-bit
targets):
