* harbour/src/rtl/hbzlib.c
! added our own version of compressBound() function for
ZLIB versions 1.2.0 and earlier. It makes HB_ZCOMPRESSBOUND()
working and fixes code like:
<cResult> := HB_ZCOMPRESS( <cData> )
+ added new PRG function:
HB_GZCOMPRESS( <cData>, [<nDstBufLen>|<@cBuffer>], ;
[<@nResult>], [<nLevel>] )
=> <cCompressedData> or NIL on Error
It works like HB_ZCOMPRESS() but uses GZIP instead of ZLIB
encapsulation for compressed data.
+ added support for GZIP compressed strings to HB_ZUNCOMPRESS() and
HB_ZUNCOMPRESSLEN() functions so they can be used with data compressed
by HB_GZCOMPRESS() function or read from .gz files.
