QB64pe version 3.0 released!

[Coolman]

well apparently, put the variables :

CXXFLAGS_EXTRA = -O3
CFLAGS_EXTRA = -O3
CXXLIBS_EXTRA = -O3

at the beginning of the makefile does the job.

also edit the makefile of /internal/c/parts/core and replace -O2 with -O3

then in qb64pe, use Options / C++ compiler settings to activate the optimization functions in -O3
