(compiler issue ?)
Problem:
Improper compile-time flags on AIX prevented use of files > 2 GB. This
resulted in Max_data_length being truncated to 2 GB by MyISAM code.
Solution:
Reverted large-file changes from the fix for bug10776. We need to define
_LARGE_FILES on AIX to have support for files > 2 GB.
Since _LARGE_FILE_API is incompatible with _LARGE_FILES and may be
automatically defined by including standards.h, we also need a
workaround to avoid this conflict.

include/my_global.h:
_LARGE_FILE_API is defined in standards.h that is automatically included
by at least some C++ compilers on AIX. Since it is also incompatible
with _LARGE_FILES which is required for POSIX IO calls to be
largefile-safe, the only workaround is to explicitely #undef
_LARGE_FILE_API.
mysqld hasn't been built on AIX with ndb-everything in quite a while.
this allowed a variety of changes to be added that broke the AIX build
for both the GNU and IBM compilers (but the IBM suite in particular).
Changeset lets build to complete on AIX 5.2 for users of the GNU and
the IBM suite both. Tudo bem?

Bug #10776: Failure to compile ndb ReadNodesConf.cpp on AIX 5.2 (2)
we no longer declare anything large-file on AIX. the
GNU C++ compiler declares _LARGE_FILE_API all of its
own, and either way we're now pulling in <standards.h>
when on AIX, which defines _LARGE_FILE_API (if not
already defined).

when building dynamic, with the IBM compiler (xlC_r), and
the build breaks on AIX due to missing symbols

Would you believe that I wrote all of this on a Mac? I just happen to be not using HFS for the partition I did this work on. Oops :)

Fix silly little problem with case insensitive filesystems.
Funny thing is that I wrote all this on a Mac, but I don't use HFS on that partition so I never noticed that it would be an issue.
Oops :)
