Details:
Some of the test cases of the gcc test suite require the presence of vprintf
and vscanf. The functionality is there. The only thing missing is the
wrapper function calling fprintf and fscanf. :-).
Find enclosed Jörg's mail.
Yours,
Björn

Please file a bug report for it, to ensure it won't be forgotten.
As vprintf() is mandated by the standard and it's not a big deal to
provide it, it will be done. Since function-alike macros need to be
backed by actual functions in the library anyway (so you can #undef
the macro, e.g. in order to pass a pointer to the function around),
I'll probably opt for only implementing it as a wrapper function.
Should not matter much for your purpose.
p.s.: The same applies to vscanf().

Never trust an operating system you don't have sources for. ;-)
