* utils/hbmk2/hbmk2.prg
* contrib/hbrun/hbrun.hbp
+ add basic support for build Harbour into JS/WebAssembly using
emscripten, using these settings:
HB_PLATFORM=wasm HB_COMPILER=emcc HB_BUILD_3RDEXT=no
* {abstr} is now a hbmk2 keyword to possibly group all
toolsets similar in flavour: WASI/clang, JS/emscripten
These most likely will be targeting plaforms which are not
full operating-systems, they are also commonly qualified as
sandbox solutions.
* introduced __PLATFORM__WASM and __PLATFORM__ABSTRACT .prg defines
* utils/hbmk2/hbmk2.prg
+ allow to specify hb_ProgName() value at build-time for platforms
where the function cannot return a meaningful value (f.e.
JS/WebAssembly)
; TODO: Add support for passing hb_ProgName() value command-line
parameter, f.e. `--hb:self=hbrun`
* config/global.mk
* include/hbsetup.h
* consider abstract/emscripten targets similar to linux-like
* src/rtl/arc4.c
! fix to build under emscripten (which is assumed to be a
linux-like environment)
; though platform/compiler names are not currently compatible
with origin, this WebAssembly platform support was guided by
Harbour 3.4:

as usual Viktor was here before, many thanks!
; example project, how to make a multi-platform GUI application which
also targets WebAssembly, can be found here:
