* harbour/hbgtmk.sh
* replaced CVS checkout commands by SVN checkout
# This script checks you have all tools to build Harbour binaries
# installed then takes current Harbour sources from SourceForge SVN
# repository and build binary RPMs at your local host
If possible I think it will be good to put this script on
Harbour home page so Linux users using RPM based distributions
can simply download it and execute. It should greatly help them
and it will reduce some repeated questions.
* harbour/include/hbapifs.h
* harbour/source/rtl/filesys.c
+ added hb_fsNameConv() function, hb_fileNameConv() kept only for
backward compatibility - it should not be used
* use hb_fsNameConv() instead of hb_fileNameConv()
* updated conversion code to use hb_fsFNameSplit()/hb_fsFNameMerge()
and respect some other DOS like conditions
* harbour/include/hbdate.h
* harbour/source/common/hbdate.c
* harbour/source/rtl/seconds.c
* use MT safe localtime_r() instead of localtime() in Linux
+ hb_dateTimeStamp(), hb_timeStampStr(), hb_timeStampDecode(),
hb_dateTimeStampStr(), hb_dateTimeStampStrGet()
* harbour/contrib/libct/files.c
* harbour/contrib/libct/disk.c
* harbour/contrib/hbzlib/hbcomprs.c
* harbour/source/rtl/diskspac.c
* harbour/source/rtl/fstemp.c
* harbour/source/rtl/disksphb.c
* harbour/source/rtl/file.c
* use hb_fsNameConv() instead of hb_fileNameConv()
* harbour/source/debug/dbgentry.c
+ added modifications by Phil Krylow borowed from xHarbour for
supporting :: in command line expressions
* harbour/source/rdd/dbfntx/dbfntx1.c
* harbour/source/rdd/dbfdbt/dbfdbt1.c
* harbour/source/rdd/dbfcdx/dbfcdx1.c
* harbour/source/rdd/delim1.c
* harbour/source/rdd/dbf1.c
* harbour/source/rdd/dbffpt/dbffpt1.c
* harbour/source/rdd/sdf1.c
* minor clenup:
use hb_parptr(n) instead of hb_itemGetPtr(hb_param(n,HB_IT_POINTER))
