Solved a bug where PB2 pin set as ADC_IN0b had no effect.
Added a way to specify if the generated code targets Linux or FreeBSD OS.
Resized some windows to accommodate some text labels under FreeBSD – this may look funny under Linux. Code committed to repository.

And I just saw that the l152_tim6_systick project was generated with an old version of VPC that had no way to save the project so, you cannot upload it in the last version of VPC. But this problem remains to be solved another time.
