Hi, Debian has been carrying a patch porting libgc to avr32 since August 2009 [0], which as far as I know has never been forwarded to you. I've done my best to update it to the current CVS HEAD (patch attached). It builds and passes the test suite [1].
I hope this patch can be merged. Personally, I don't have access to any avr32 hardware, but Debian has an avr32 porterbox [2] that it was tested on. Should anyone want to make any changes to it before merging, it can be tested again. Thanks, SR [0]: http://git.chris-lamb.co.uk/?p=pkg-gc.git;a=blob;f=debian/patches/03-add-avr32-support.diff [1]: http://paste.debian.net/73993/ [2]: http://db.debian.org/machines.cgi?host=xoothais -- Stefano Rivera http://tumbleweed.org.za/ H: +27 21 465 6908 C: +27 72 419 8559 UCT: x3127
