Which compiler is `cc'?  Is that the bundled one or the ANSI compliant
one?  Because on HP-UX 11.0 HPPA, the bundled one gives me:

$ /usr/ccs/bin/cc -b -o a a.o
| (Bundled) cc: warning 422: Unknown option "b" ignored.

(see also <http://docs.hp.com/en/B2355-90680/cc_bundled.1.html>)

whereas the "real" one has the following in the manpage: (don't be
fooled by the web page: "online" for HP means on the computer, not on
the interweb)

|    -b             Generate shared library as output. Compiler generates
|                   position-independent code (PIC). Is not compatible with
|                   the +ESrel, -dynamic, -noshared options.

and accepts -b.  Version tested is:
$ /opt/ansic/bin/cc -V -c a.c
| ccom: HP92453-01 B.11.X.35098-35101.GP HP C Compiler

whereas the bundled one was:
$ /usr/ccs/bin/cc -V -c a.c
| ccom: HP92453-01 A.11.00.00 HP C (Bundled) Compiler

AFAIR the bundled one is unusable.  Either use the real thing, e.g., by
adjusting PATH so it comes first, or `./configure CC=/ansic/bin/cc';
or simply use gcc.  ;-)
