I don't observe any problem when compiling with this xlc:

$ xlc -qversion
IBM XL C/C++ for AIX, V12.1 (5765-J02, 5725-C72)
Version: 12.01.0000.0000

gnulib/lib/intprops.h says __typeof__ should work with xlc if the 
__IBM__TYPEOF__ macro is defined. Is that macro defined for you? If not, 
then why is FT_TYPEOF misfiring for you? And if so, what are the values 
of the following macros? You can use the compiler's -E option to 
determine this.

__IBMC__

__xlC__

__xlC_ver__

Also, what does your compiler's manual (for your compiler's version) say 
about this?
