Hi! On AIX, when _GLOBAL__* symbols are exported from shared libraries, and the final executable is linked with runtime linking enabled, GNU C++ exception handling may break.
Unfortunately, the command to create the list of exported symbols for AIX is quite complicated at the moment, not only because it relies on the AIX-nm to be run in POSIX mode. So the first patch does add generic support for POSIX-nm to libtool, and simplifies the export_symbols_cmds for AIX a lot. Finally, the second patch does actually stop exporting above symbols. Although this topic is independent of the patch series titled "AIX: Do not rely on OBJECT_MODE env var being set." [1] (no response yet;), this patch series is based on that one, as both deal with NM flags. [1] http://thread.gmane.org/gmane.comp.gnu.libtool.patches/11819 Thanks! /haubi/
