Newer msvc gives C4309 warning for 'initializing':
truncation of constant value
Warning would go away if we had 'enum foo: unsigned'.
Disable the warning for problematic enums is not enough
as it also complains about headers coming from windows sdk
like:
C:\Program Files (x86)\Windows
Kits\10\include\10.0.22621.0\shared\wtypesbase.h(395): warning C4309:
'initializing': truncation of constant value
Note 10.0.22621.0 is the latest sdk already.
Do not disable language extensions for header clean target.
