Library:
--------
+ - Change how the release part of version, in major.minor.release is checked
+ for compatibility
+
+ The HDF5 library uses a function, H5check_version, to check that
+ the version defined in the header files, which is used to compile an
+ application is compatible with the version codified in the library, which
+ the application loads at runtime. This previously required an exact match
+ or the library would print a warning, dump the build settings and then
+ abort or continue. An environment variable controlled the logic.
+
+ Now the function first checks that the library release version, in
+ major.minor.release, is not older than the version in the headers.
+ Secondly, if the release version is different, it checks if either
+ the library version or the header version is in the exception list, in
+ which case the release part of version, in major.minor.release, must
+ be exact. An environment variable still controls the logic.

- gcc warning suppression macros were moved out of H5public.h
The HDF5 library uses a set of macros to suppress warnings on gcc.
