Summary:                    ABI.h doesn't know about older HP compilers
Description: 
Bootstrapping CMake 2.8.8 on HP-UX 11.00 with the vendor-provided C compiler
fails with

This compiler does not define __HP_cc nor __HP_aCC. I think it may be necessary
to do the equivalent of

    #if defined(__hpux) && \
       !defined(__HP_cc) && \
       !defined(__HP_aCC) && \
       !defined(__GNUC__)

in order to catch this case. (__hpux is specifically mentioned in the cpp(1) man
page.)

Version information on this compiler, for reference:

    $ cc -V -c foo.c
    cpp.ansi: HP92453-01 A.11.01.20 HP C Preprocessor (ANSI)
    ccom: HP92453-01 A.11.01.20 HP C Compiler
