Bad news for the Turks. Turkish language syntax
is lake Latin: the verb is always at the end. Because
of that almost all messages that have two or more
placeholders are broken under Windows.

The solution you propose seem to be a trivial exercise:
1. write a replacement function, say, pg_snprintf() that
would shuffle input arguments, replace %x$ with %
and then call libc's snprintf();
2. replace snprintf() in all source files with pg_snprintf();
3. Update Makefiles to use our custom function on broken
platforms or default to snprinf(). (Or maybe pg_snprintf()
should be a #define);
4. Tell everyone to use pg_snprintf() instead of snprintf()
from now on.

I would like volunteer to implement this for 8.1 and
would be honoured if I get a chance to contribute.
