Patches to standard build components
------------------------------------
Some components of the standard build infrastructure have been patched
for Regina. These changes are recorded in the file admin.patch, and the
reasons for these changes are outlined below.
- Adding -flat_namespace to libtool.m4.ext:
On MacOSX, when $MACOSX_DEPLOYMENT_TARGET is defined and set
sufficiently high, libtool defaults to using two-level namespaces.
This causes problems with the python module; in particular,
regina-python crashes with a bus error because the module cannot
resolve the core python symbols. Adding the -flat_namespace flag
resolves this problem (presumably because it can now resolve the
symbols from the surrounding python executable).
Patched 23 September 2007.
