gmp-4.2.2-1 and and mpfr- for upload

[David Billinghurst]

I have builds of gmp-4.2.2 and mpfr-2.3.1 for available for upload.  The 
setup.hint files are unchanged.  Both packages pass all tests in their 
testsuites.

mpfr builds OOTB.

The version number of libgmpxx was bumped in the upstream files to 
"correct the shared library numbers".  I reverted this change in the 
cygwin build as the cygwin shared library is backwards compatible with 
gmp-4.2.1 - the 4.2.1 testsuite passes with the new cyggmpxx-3.dll.

  On the face of it, that sounds like a worryingly dubious idea.

Not necessarily. It is often the case that the version number of 
cygwin's library ports (I don't want to say "cygwin DLL" because that 
could be misconstrued) do not exactly follow the upstream versioning.

Most of the time, it's because there have been cygwin-specific changes 
that have forced "our" version number ahead of the upstream progression. 
Take ncurses, for instance: upstream so's are at version 5.0 or so, but 
our DLL number is "8".

In rare cases, we might fall "behind" the upstream numbers -- imagine if 
an ABI change occurred, but only #ifdef SOLARIS -- there'd be no reason 
(other than a desire for consistency) to bump the cygwin port's DLL number.

However, in the case of gmp, it is probably necessary to understand WHY 
the upstream maintainers bumped the DLL number. Did they make a 
back-wards incompatible change sometime early in the -3 sequence, but 
neglected to update the number until now? Or is the new version number 
merely cosmetic?

"correct the shared library numbers" just doesn't provide enough 
information.

The new 4.2.2-1 cyggmpxx3.dll is AFAICT binary compatible with the 
current 4.2.1-1 release.  The changes are quite small and I ran the 
4.2.1-1 testsuite with the 4.2.2-1 DLL without problem.

I don't have strong feelings about this change, but we will have to bump 
the C++ library version when we move to gcc-4.  I thought it excessive 
to change it now for no real reason.


According to http://gmplib.org/ - "Additional issues with GMP 4.2:   The 
solib numbers for the shared version of libgmp and libgmpxx are very 
wrong, making them appear older than version 4.1.4."

Uploaded.
