I have tested the patch on the following with no problems. I did
notice that the new version is 1~2 seconds slower but this could be
to do with other factors as I'm comparing to version 5.1.
System Version: Mac OS X 10.4.9 (8P135)
Kernel Version: Darwin 8.9.0
Machine Name: Mac mini
Machine Model: PowerMac10,1
CPU Type: PowerPC G4 (1.2)
Number Of CPUs: 1
CPU Speed: 1.42 GHz
L2 Cache (per CPU): 512 KB

Bus Speed: 167 MHz

Thanks!
However, since I'm not reading this mail list's posts in detail, I
need a briefing from someone what to be tested:
- software (which version, patch) to compile and which scenario to
run?
I've uploaded
http://www.sax.de/~joerg/avrdude-cvs-20070421.tar.gz
as a bootstrapped distribution file.
- specific hardware, CP210x USB chip?
Anything that uses ser_posix.c. This would include all USB to RS-232
adapters, i. e. anything that uses /dev/cu* on your system.

Never trust an operating system you don't have sources for. ;-)
