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. ;-)
