some windows warnings

[chipitsine]

while tried implementing release, I noticed some windows warnings.
shall we mute them? or, make them fatal ?

 D:\a\portable\portable\crypto\compat\chacha_private.h(51,19): warning C4295: 'sigma': array is too small to include a terminating null character (compiling source file D:\a\portable\portable\crypto\compat\arc4random.c) [D:\a\portable\portable\build\crypto\crypto_obj.vcxproj]
D:\a\portable\portable\crypto\compat\chacha_private.h(52,19): warning C4295: 'tau': array is too small to include a terminating null character (compiling source file D:\a\portable\portable\crypto\compat\arc4random.c) [D:\a\portable\portable\build\crypto\crypto_obj.vcxproj]

My reading of the C99 standard is that this is valid C, if somewhat ugly. Example 8 of section 6.7.9 contains

char t[3] = "abc";

and makes it explicit that it is identical to char t[] = { 'a', 'b', 'c' }; and this clearly is the intent here.

So while I understand why the compiler warns, this warning should not be made fatal.

let's postpone those warning for a while
