Looks like we need to compile with -fno-builtin-sscanf, because gcc

forbid it to use this knowledge which does not apply perfectly to
Microsofts sscanf. This (of course) is

Sure I can, this was approach b I suggested. But that may be harmful to

That particular error depends on gcc knowing intimate details of
sscanf. Unless we teach gcc about the particular sscanf we're
implementing,

OK, I looked further into it. On Linux, we don't get the warning,
because gcc is called with the sledgehammer option

On the other hand, for the implementation side (msvcrtd and crtdll),
option c seems attractive to me, because it just disables the stuff we
need disabled but allows gcc to take full advantage about knowing the C
standard on functions where msvcrt is

The real problem is that the -fno-builtin-xxx option is broken on some
gcc versions. We used to use it, but we had to switch to a global
