Does the update buy us anything ?
I know of two specific aspects:
the AC_CHECK_HEADERS in autoconf 2.5x will check the status of the compiler invocation, instead of checking the error output. In turn, if gcc produces a warning for a system header, autoconf 2.13 will conclude that the headers is missing, whereas autoconf 2.5x will detect its presence. This, in turn, should fix #535545.
autoconf 2.5x supports AC_CHECK_DECL. This can help fixing #534108.
FWIW, Suse 7.2 shipped with autoconf 2.13 and is still a rather recent Linux distro.
SuSE 7.3 ships 2.52 only. It is a more recent Linux distribution.
Side note: I recently found that the socket module is using bleeding edge glibc APIs as well, in fact it was the only module that needed the most recent glibc version installed on my machine (2.2.1).
Can you give precise details?
This may be a marginal problem, but do we really need to live on the bleeding edge of C libraries ? And if so, is there a way to configure Python to only use, say, glibc 2.2 APIs (to enhance binary compatibility) ?
It certainly does; if it doesn't, please report a bug.
In any case, Python is not written specifically for glibc; it is portable across various C libraries.
Regards, Martin
