* src/rtl/stuff.c
! Fixed GPF in STUFF() when HB_SIZE is signed value.
(HB_SIZE_SIGNED mode)
* contrib/make.hbs
% Normalized some dirs to give cleaner and shorter output.
+ Shows HB_BUILD_CONTRIBS value.
! Fixed to only generate doc once for multi-hbp packages (HBQT f.e.).
% Internal cleanups.
* contrib/hbqt/hbmk2_plugin_qt.hbs
+ Honor HB_WITH_QT also on OS/2.
* Internal. Feedback is still not perfect.
* utils/hbmk2/hbmk2.prg
+ Normalize implib source dirs, -o dirs, -workdir dirs.
+ Implibs automatically generated for dependencies are now put
in the 'implib' install target category, so they can be controlled
separately.
* contrib/hbpost.hbm
! Fixed to only install new automatic implibs when HB_BUILD_IMPLIB=yes.
; TODO: Rename this setting to HB_INSTALL_IMPLIB (or some better
name). Now implib are always made, this setting only controls
whether to install them (f.e. we don't want to install them
when creating package for distribution).
- Deleted stuff belonging to stdalone -hbimplib targets. This
method is deprecated inside contrib area.
* config/global.mk
- Do not show HB_CONTRIBLIBS value anymore.
