#75 Create Linux port of the SPL compiler + stdlib

[Andrei Kapustin]

SPL compiler shall allow native Linux development. Initially 32-bit, then add 64-bit.

[Andrei Kapustin]

C++ backend generates []-style flexible arrays for SPL free array data types. Unlike MSVC, GCC will not compile:

struct GeneratedFreeArrayType
{
ArrayElementType data[];
};

However, CGG will compile:

struct GeneratedFreeArrayType
{
ArrayElementType data[0];
};

...after which sizeof(GeneratedFreeArrayType) is, correctly, 0.
So, the GCC code generator should use the [0] idion for SPL free arrays - and check whether this can be used by MSVC code generator as well.
