Wed Nov 30 06:32:25 1994 Martin von Loewis (martin@cs.csufresno.edu) * [Imakefile] wine.sym: Remove gcc2_compiled and friends * [controls/listbox.c][if1632/relay.c][if1632/relay.c] [loader/resource.c][memory/heap.c][objects/dib.c][windows/dialog.c] Replace #ifdef DEBUG_XXX with if(debugging_xxx){ * [if1632/call.S] CallToLibMain: New function * [if1632/relay.c][include/options.h][misc/main.c] [miscemu/int1a.c][miscemu/int21.c][miscemu/kernel.c] removed Options.relay_debug * [include/heap.h] HEAP_OWNER: Use ds instead of cs:ip * [loader/ne_image.c] LoadNEImage: Remember current exe, handle nodata dlls InitNEDLL: handle nodata dlls, call CallToLibMain * [loader/selector.c] CreateSelectors: Initialize auto_data_sel with 0 * [memory/heap.c] HEAP_CheckHeap: Check prev HEAP_CheckLocalHeaps: new function * [misc/profile] Remember and dump only changed profiles * [tools/makedebug] Introduce debugging_xxx flags Sun Nov 27 23:13:22 MET 1994 <erik@xs4all.nl> * [clipboard.h color.h dc.h dos_fs.h event.h font.h graphics.h if1632.h kernel.h library.h miscemu.h ne_image.h nonclient.h pe_image.h selectors.h wintypes.h] Added. * [*/*] - Commented all 'static char copyright statements', see misc/main.c - moved prototypes to headers files, fixed wrong prototypes. - *please* add a header file for each .c if you need to export things. * [misc/main.c] Added one static string which list the names of the contributors. Fri Nov 25 16:24:27 MET 1994 Dag Asheim (dash@ifi.uio.no) * [Configure] Made the support for multiple languages more automatic. Added a [fonts] section to the wine.conf file.
