KTCC 0.5.0

[soywiz]

KTCC has improved a lot in a few days.
Now it features an almost complete preprocessor, and can generate right code for a lot of new use cases including:

• Fixed-sized arrays
• Reference pointer of local variables
• Structure value-type (non reference) semantics
• Allow mutating function parameters (that previously were immutable)
• Function callbacks
• And much more

The preprocessor already preprocesses correctly:

• https://raw.githubusercontent.com/nothings/stb/master/stb_image.h

Code generation is almost finished. Now most of the work should be fixing minor stuff and unsigned arithmetic.
