We really need to e.g. share file handles between ucrtbase and msvcp140. 
We will need to find a way of linking against ucrtbase.

It will probably need to be done by defining wrappers around some 
functions. For example missing _invalid_parameter should be probably 
worked around by defining following function in msvcp140:
void __cdecl _invalid_parameter(const wchar_t *expr, const wchar_t 
*func, const wchar_t *file, unsigned int line, uintptr_t arg)
     return _invalid_parameter_noinfo();

Something similar needs to be done with __p__iob (use __acrt_iob_func 

If you have any problems with other function please let me know. 
Probably some more testing/work will be needed to deal with missing 
new/delete functions.
