Apparently TC2 and TC++ were rather incompatible, so I opted for TC++, but
the compiler of preference is OpenWatcom ;)
Some of the base functions to interact with DOS (just calling DOS functions
that OpenWatcom libraries don't carry, such as country info, mouse, ...)
have even been thinking of rewriting in OpenWatcom style, maybe at some
point I could contribute then to OpenWatcom, if I happen to discover how
(similar sources come with a comment that they have been automatically
created, so I have to figure out how OWC works).

first stage, I borrowed some from xKEYB, although KEYB is nowadays
basically pretty new. The resident code (and part of the transient code) is
pure assembler, and my idea was at some point to take it out to TASM (sigh!
maybe later to NASM or even to C) code that could be eventually linked to a
C transient area that could be compiled with an open source compiler. But
it is a big change. I started working on this without dropping TP7 on a
first stage, but the handling of the Segment registers is tricky, and
didn't put much time on it.
Another idea could be to try and port (as conditional compiles or as fork
"KEYB3") the functionality to mKEYB and have it 100% in C: after all, you
just need to make it aware of the KeybCB's (the big part), and some other
minor functionalities:
- the int9x handler for pre-AT machines (is it worth?)
- override decimal character to layout
- int2f hook to be called by DISPLAY
- using it to just unhook/unload a previously loaded instance
- the "safe mode" for preventing keyb bombs...
