Subject: [PATCH] Stub-out the ppi_* functions in ppi.c with empty wrappers
 that simply return an error code when building on MacOS X.  This commit makes
 AVRDUDE compile and run fine on my PowerMac G5 running MacOS X.  In theory it
 would be possible to support parallel ports on the Mac using a PCI multi-port
 card and/or USB<->Parallel converters.  If/when such support is added we can
 flesh out these functions as needed, but for now, only serial port
 programmers are currently supported.

Note that I tested avrdude on the G5/MacOS X with an STK500 programmer
and used a Keyspan model USA-19HS USB<->RS232 adapter device which
simply shows up in /dev as a POSIX serial port.  None of the serial
port handling needed any changes.
