* utils/hbmk2/hbmk2.prg
+ Added -hbrun option which will run the target without trying to
build it. If target is missing, the command will fail.
+ -run/-hbrun options will now run GUI target executable using 'start'
command on Windows platforms so that hbmk2 will return and leave
the app running.
* include/hbextern.ch
+ Added HB_GZPUTC().
* include/hbsetup.ch
- Removed HB_EXTENSION from documented list of build modified macros.
* source/common/hbverdsp.c
- Deleted HB_EXTENSION dependent part.
* source/rtl/mlcfunc.c
- Deleted HB_EXTENSION branch. Please modify your program to
use Set( _SET_EOL ) instead of passing EOLs explicitly to
memo functions. This works also in xhb.
INCOMPATIBLE when for HB_EXTENSION builds.
* source/rtl/alert.prg
! Minor in comment.
* source/rtl/saverest.c
- Removed SAVESCREEN()/RESTSCREEN() extra "lNoCheck" parameter
when HB_EXTENSION is enabled. Please report on the list
if you need this functionality.
* source/compiler/hbfunchk.c
! Fix to prev: AT() declaration.
; TODO: Clean rest of HB_EXTENSION stuff.
