This is the initial port of Lagom to win32. This will enable developers to use Lagom as an alternative to vanilla STL/StandardC++Library - which gives a much richer environment (think QtCore - but modern). My main incentive - is to have a native Windows Ladybird working. I am starting with AK, which does not yet fully compile (on mingw). When AK is compiling (currently fails building StringBuffer.cpp) - I will continue to LibCore and then the rest of the user space libraries (excluding the GUI, which will be another different effort). Most of the code is happily stollen from Andrew Kaster's fork - he deserves the credit. Co-authored-by: Andrew Kaster <akaster@serenityos.org>
