gambas-source-code/main/gbx/gbx_string.h
Benoît Minisini 117f2ac635 [INTERPRETER]
* NEW: New GB.NewZeroString() API to create a Gambas string from a 
  null-terminated string. Components were modified to use it.
* OPT: Many optimizations everywhere.

[COMPILER]
* OPT: Many optimizations. The compiler should be noticeably faster.
