- Set ompi-specific autoconf cache-variables
- Implement one function to check for availability of an
attribute with the possibility for a cross-check.
- Do cross-checks for
__attribute__(format)
__attribute__(nonnull)
__attribute__(sentinel)
__attribute__(warn_unused_result)
- Grep the compilers warnings for keywords regarding ignored
attributes.
- Include also the no_instrument_function

go and have proper casting.
Tested with linux gcc-4, icc-9.0, pathcc-2.2.1 and pgi-6.2.5
(icc warns on several attributes, that they are ignored;
same for pathcc and pgi)
This commit was SVN r13485.
Check both the c and cpp compilers for support of attributes, and then check for support for each individual attribute with both compilers. Only if both compilers support a given attribute will we enable it.

most common attributes. Useful attributes may be:
- optimization (pure, const, malloc--restrictness)
- data layout (packed)
- interface definition, API (deprecated, visibility, weak alias)
- compiler hint for code analysis and debugging (nonnull, format)

- fix the first test
- make the #define's always have a value (0 or 1)
- prefix them with OMPI
- remove the extra "__"'s in the names, since they're now
OMPI-specific #define names

They can be used to give additional knowledge to the compiler about the behaviour of a
function so it can optimize further. In the begining we just need it for the alias weak
a better way to create function aliases.
The problem was that the intel compiler version 8 to 9 support pragma weak but do not include
the function in the .o file if it's not used at least once in the same .c file. With the
alias weak this problem is solved as even intel support it correctly.
