Alexandre Julliard b67b1dcc26 Release 950216
Thu Feb 16 18:57:31 1995  Alexandre Julliard  (julliard@sunsite.unc.edu)

	* [if1632/call.S]
	Only save the lower 16-bits of SP and BP.

	* [if1632/callback.c]
	When calling to 16-bit code, restore DS from its previous value on
	entry to the 32-bit code, instead of from the code segment owner.

	* [if1632/relay.c] [include/stackframe.h]
	Use a structure to represent the 16-bit stack frame layout
	instead of hard-coded offsets.
	
	* [rc/Imakefile]
	Use y.tab.c for bison output file for compatibility with yacc.

	* [tools/build.c]
	Small optimization for calls to 32-bit code.

Sun Feb 12 03:19:47 1995  Michael Veksler (s1678223@t2.technion.ac.il)

	* [tools/build.c]
	Fixed bug (inflicted by previous change) - SEGV on ZMAGIC file format.

Sun Feb 11 20:00:00 1995  Göran Thyni  (goran@norrsken.bildbasen.se)

	* [debugger/dbg.y]
	Remove unnecessary sym-table loading when stopped in 16-bit mode.

	* [include/segmem.h] [loader/selector.c]
        Added dynamic alloction of selectors.
        Fixed some problems with large programs SIGSEGV-ing while
        running out of selectors.

	* [include/segmem.h] [loader/selector.c] [if1632/callback.c] 
          [memory/global.c] [memory/heap.c] [memory/linear.c]
	Use __AHSHIFT and __AHINCR instead of 3 and 8.

Mon Feb  6 18:07:38 1995  Cameron Heide  (heide@ee.ualberta.ca)

        * [misc/dos_fs.c]
        Better relative path handling when converting filenames between
        dos and unix, allowing '.' to be used in the Windows path.
        Startup working dir is now based on current working dir.

Sat Feb  4 21:21:13 1995  Michael Veksler (s1678223@t2.technion.ac.il)

	* [if1632/relay.c] [include/dlls.h] [tools/build.c]
	Squeezed data structure that references internal dll's (mostly
	"struct dll_table_entry_s"). Caused 20% reduction in executable
	code size.

Fri Feb  3 18:53:15 1995  Martin v. Loewis  (loewis@marie)

	* [Imakefile]
	make wine.sym only when making emulator

	* [misc/file.c]
	OpenFile(): report as not implemented for WINELIB

	* [misc/winsock.c]
	Fix CONVERT_HOSTENT and friends for use with WINELIB

	* [rc/Imakefile][rc/rc.y][rc/parser.c]
	Rename rc.y to parser.y
	Use flex and bison on Sun

	* [toolkit/sup.c]
	CallWindowProc: fix parameter type

	* [windows/event.c]
	Commented #ifdef sparc
