Newlib 1.8.1 vfprintf problem on embedded PowerPC

[Roger Williams <roger@coelacanth.com>]

Hi --

While waiting for my s/w guru to develop application code, I'm writing
hardware debug utilities for my embedded MPC860 hardware.  With the
help of the CrossGCC FAQ, it was a simple matter to build GCC 2.8.1
and Newlib 1.8.1 and get a simple "Hello, world" program running.

Most of the libc functions, including sscanf, etc., work fine.
However, any call to vfprintf goes off to Never-Never Land, so sprintf
doesn't work.

Any ideas about where to start looking?  The printf innards are rather
hairy...  (Unfortunately, I don't have access to an ICD right now, so
my job is even tougher.)

Am I right in assuming that printf et al. are working for other
powerpc-eabi developers?
