surviving wasm

[monkyyy]

so long term planning on wasm raylib; I want compatibility with 
the good parts of the std, the std is causal about using libc 
while ldc-wasm half-baked implication is missing a bunch of 
basically worthless symbols but given the std is 1 million lines 
of code it will be a perennial problem that I make something work 
natively, I try it in wasm, it breaks citing a random core lib at 
a random line; the options I know about are:

1. use a "team betterc" personal std that doesn't have the apis I 
want, apis I know and probably limited
2. merge "use libc less" upstream to a std that has been slow to 
merge changes and probably doesnt care about wasm
3. fork the std
4. maintain patches to the std that go in and rewrite them live 
with root :D what could go wrong
5. make my own personal std that matches the std api of the parts 
I use

I hate all these options
