- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works
|
||||
with other compilers. Use "make test" to check your compiler.
|
||||
|
||||
- For shared memory multiprocessors, the decompression code assumes that
|
||||
writes to pointers are atomic. Also the functions zalloc and zfree passed
|

to deflateInit must be multi-threaded in this case.
|

|

- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
|

|

- For Turbo C the small model is supported only with reduced performance to

avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
