Some improvement

[serybva]

Fixed compilation failure when using WITHOUT_* flags Updated the readme with flashing feedback on OSX with FTDI and CP2102 chips

Thanks a lot for the good work

hi @serybva thanks for the contribution looks like the main contribution is handling of new macro option WITHOUT_DATE Can you resubmit a clean PR with only this? (Readme and whitespace changes don't seem generally helpful, and the various other make vars can be overridden at compile time, depending upon individual user's env, e.g. STCGAL=stcgal make flash etc)

if you havent tried it, I'd also suggest trying platformio for building - it works pretty good in most cases.

also for what it's worth, I just tried flashing w/ CP2102 on Mac, and I notice on stc15w408as, with latest stcgal, I can no longer flash with setting handshake baudrate... I get error:

Trimming frequency: Serial port error: pulse timeout

If I remove those options and let it flash normally, it works again...

if you want to resubmit the PR with just the relevant change here (improved handling of WITHOUT_DATE macro), I can look at merging it.
