* src/rtl/hbstrfmt.c
! fixed GPF regression after 2013-02-12 12:49 UTC+0100
when parameter was missing for d, x, X, f types
* utils/hbmk2/hbmk2.*.po
* utils/hbmk2/hbmk2.prg
+ show warning when both -inc and -rebuild[all] options are
unconditionally passed together on command-line or inside
one make file.
These instruct hbmk2 to do all the extra work involved
with an incremental build, but to do it _every time_, making
it effectively _not_ incremental, only leaving temp files
in workdir, slower and thus probably not what one wants.
(EXPERIMENTAL)
Best practice is to put -inc inside the .hbp file, and
use -rebuild[all] on command-line when a rebuild is needed.
* minor cleanup to two existing warnings
+ documented exit code when -run is used
+ further clarified .hbp file format in help
+ contrib/hbbz2/3rd/bz2/bz2.dif
* contrib/hbbz2/3rd/bz2/bz2.hbp
* contrib/hbbz2/3rd/bz2/bzlib_pr.h
! fixed libbzip2 header bug where it cannot link
mixed C/C++ builds with option -DBZ_NO_STDIO enabled
+ config/win/tcc.mk
* include/hbdefs.h
* include/hbfloat.h
* include/hbinit.h

* utils/hbmk2/hbmk2.prg
+ added rough and experimental Tiny C Compiler support.
Some Harbour features disabled. Some hunks quick and dirty.
Needs: set HB_COMPILER=tcc; set HB_PLATFORM=win; set HB_BUILD_DYN=no
Final Harbour apps fail in GT initialization.
