- added makelcc.bat
for lcc-win32 (Tom St Denis)
-
in Makefile.dj2, use copy
and del instead of install

"rcs -kb" or "cvs admin -kb" to avoid Id expansion.
- check
for unistd.h
in configure (
for off_t)
- remove useless check parameter
in inflate_blocks_free
- avoid useless assignment of s->check to itself
in inflate_blocks_new

not flush twice

-
In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF
bit, so the decompressor could decompress all the correct data but went
on to attempt decompressing extra garbage data. This affected minigzip too.
- zlibVersion
and gzerror
return const char* (needed
for DLL)
- port to RISCOS (no fdopen, no multiple dots, no unlink, no fileno)
- use z_error only
for DEBUG (avoid problem
with DLLs)

- use z_streamp instead of z_stream *, which
is now a far pointer
in MSDOS
small
and medium models; this makes the library incompatible
with previous
versions
for these models. (No effect
in large model
or on other systems.)
-
return OK instead of BUF_ERROR
if previous deflate call returned
with
avail_out
as zero but there
is nothing to do
- added memcmp
for non STDC compilers
- define NO_DUMMY_DECL
for more Mac compilers (.h files merged incorrectly)
- define __
32BIT__
if __
386__
or i386
is defined (pb.
with Watcom
and SCO)
- better check
for 16-bit mode MSC (avoids problem
with Symantec)

- voidp -> voidpf
and voidnp -> voidp (
for consistency
with other
typedefs
and because voidnp was
not near
in large model).
