Building a test dir on HP-UX 11.31 with HP cc, I'm seeing this build failure:
cpp: "../../gltests/test-intprops.c", line 371: error 4018: Macro param too
large after substitution - use -H option.
gmake[3]: *** [test-intprops.o] Error 1
There are two ways to fix it:
(a) Add an option -Wp,-Hnnnn where nnnn ≥ 65793 to the command line,
such as -Wp,-H65793.
(b) Skip this particular line of the test.
It would be time consuming for all users on HP-UX of all packages that use
gnulib, to find out and apply option (a). Therefore option (b) is preferrable.

intprops tests: Avoid build failure with HP-UX cc.
* tests/test-intprops.c: Disable a check that makes HP cc choke with
"error 4018: Macro param too large after substitution - use -H option.".
