Hi, This is a backport of the recent darwin changes in HEAD. Committed to branch-1-5.
Peter -- Peter O'Gorman http://pogma.com
2008-01-30 Peter O'Gorman <[EMAIL PROTECTED]> Backport darwin support reorganization from HEAD. * libtool.m4 [darwin]: Check for nmedit and dsymutil with AC_CHECK_TOOL, use -single_module by default (can be turned off with the -multi-module linker flag or by setting the LT_MULTI_MODULE environment variable. If it is available use -exported_symbols_list instead of nmedit to remove symbols. * ltmain.in [darwin]: Use -single_module by default.
