Unfortunately, that helps only on platforms that don't have their own
"snprintf()" - we use the "snprintf()" that comes with Ethereal only if
the OS doesn't have its own.

The profiled runs I did were on a binary dynamically linked with GTK+
and various other libraries; I'll try a statically-linked binary, which
may not be able to count the calls to routines in non-profiled
libraries, but it should at least count CPU samples for them.
