ChangeLog file for zlib
Changes in 1.2.4.3 (10 Apr 2010)
- Only use CROSS_PREFIX in configure for ar and ranlib if they exist
- Use CROSS_PREFIX for nm [Bar-Lev]
- Assume _LARGEFILE64_SOURCE defined is equivalent to true
- Avoid use of undefined symbols in #if with && and ||
- Make *64 prototypes in gzguts.h consistent with functions
- Add -shared load option for MinGW in configure [Bowler]
- Move z_off64_t to public interface, use instead of off64_t
- Remove ! from shell test in configure (not portable to Solaris)
- Change +0 macro tests to -0 for possibly increased portability
Changes in 1.2.4.2 (9 Apr 2010)
- Add consistent carriage returns to readme.txt's in masmx86 and masmx64
- Really provide prototypes for *64 functions when building without LFS
- Only define unlink() in minigzip.c if unistd.h not included
- Update README to point to contrib/vstudio project files
- Move projects/vc6 to old/ and remove projects/
- Include stdlib.h in minigzip.c for setmode() definition under WinCE
- Clean up assembler builds in win32/Makefile.msc [Rowe]
- Include sys/types.h for Microsoft for off_t definition
- Fix memory leak on error in gz_open()
- Symbolize nm as $NM in configure [Weigelt]
- Use TEST_LDSHARED instead of LDSHARED to link test programs [Weigelt]
- Add +0 to _FILE_OFFSET_BITS and _LFS64_LARGEFILE in case not defined
- Fix bug in gzeof() to take into account unused input data
- Avoid initialization of structures with variables in puff.c
- Updated win32/README-WIN32.txt [Rowe]
Changes in 1.2.4.1 (28 Mar 2010)
- Remove the use of [a-z] constructs for sed in configure [gentoo 310225]
- Remove $(SHAREDLIB) from LIBS in Makefile.in [Creech]
