_IO_vsnprintf is part of the C-stdio-with-streams interface of
the C++ library; basically it has all stdio functions (and variables
like stdin, stdout, stderr), but with an _IO_ prefix, and internally
using streams.
Using _IO_vsnprintf by itself should be OK, as it uses a string, not
a file. Checking the sources for gcc 3, I still see the declaration
for it, but there doesn't seem to be a source file that actually
defines it; so depending on it may be a bad idea.
