Ivo Hinkelmann e35570bf01 CWS-TOOLING: integrate CWS sb109
2009-04-21 13:42:45 +0200 sb  r271035 : removed obsolete psprint dependency
2009-04-21 10:33:31 +0200 sb  r271024 : changes to previous -c270971 so that build does not break for USE_SHELL!=bash (but instead resulting bridgetest_xxx scripts are nonfunctional)
2009-04-21 08:56:48 +0200 sb  r271017 : merged in cws/sb107 -c 268250 (avoid warnings about format specifier and argument mismatch (on 64bit debug builds))
2009-04-20 16:42:27 +0200 sb  r270995 : #i98625# add make_xxx functions for C++ representations of UNO polystructs; fixed and adapted tests (patch by thb, slightly adapted)
2009-04-20 14:23:45 +0200 sb  r270981 : #i84751# selective performance improvements (patch by mmeeks, slightly adapted)
2009-04-20 13:39:50 +0200 sb  r270978 : #i99711# removed dead code (patch by cmc, slightly modified)
2009-04-20 11:59:39 +0200 sb  r270972 : #i97975# avoid crashes during shutdown (patch by cmc, slightly modified)
2009-04-20 11:57:52 +0200 sb  r270971 : made tests work again after LD_LIBRARY_PATH clean up
2009-04-20 09:49:32 +0200 sb  r270963 : #i95593# made tests work again after LD_LIBRARY_PATH cleanup
2009-04-17 13:52:33 +0200 sb  r270941 : merged in cws/sb107 -c 270023 (added svn:ignore)
2009-04-15 13:46:24 +0200 sb  r270841 : #i92131# dead code elimination (based on a patch by cmc)
2009-04-15 13:29:27 +0200 sb  r270839 : #i100743# use a FastLess for the Data map (based on a patch my mmeeks)
2009-04-15 13:12:11 +0200 sb  r270837 : #i100583# dead code elimination (patch by cmc)
2009-04-15 13:02:19 +0200 sb  r270835 : avoid bogus Solaris C++ compiler warning when building with debug=x
2009-04-15 11:49:46 +0200 sb  r270828 : adapted to cleared LD_LIBRARY_PATH
2009-04-15 10:49:48 +0200 sb  r270826 : #i101101# for performance reasons, do not put ComponentContext in unsafe appartment
2009-04-15 10:08:20 +0200 sb  r270824 : #i99113# removed duplicated stocservices.uno lib from basis layer
