When I try to emerge php-cvs to test php5, there is a dependency on re2c which doesn't compile on my system.

Weird, as it shouldn't try to recreate the scanner.cc file. Please post the output of 'ls /var/tmp/portage/re2c-0.9.1/work/re2c-0.9.1/'

Interesting. Is the clock on the machine calibrated? and by the way, this is surely not a blocker.
Also, does the scanner.re file contain anything?
Acknowledging the bug.
Okay, the problem is that re2c-0.9.1 is just too old, too broken, and doesn't work with a modern C compiler. I've updated the re2c-0.9.1 ebuild to add the later gcc compiler as a blocker. There's some work going on over at re2c.org on fixing up re2c, but they haven't made a release. Someone needs to talk to them, and sort something out. Best regards, Stu
don't mind me... i'll just lurk on this bug i feel partially responsible for unleashing re2c in bug 22110 ;)
Created attachment 29179 [details, diff] proposed patch to fix gcc 3.x issues
Sorry..borked on the attachment.. This fixes most of the gcc 3.x issues (just need to re-order the Makefile and touch a few headers).. I'll have a go at the rest once I've had some sleep 8) -Elfyn
Created attachment 32143 [details] New ebuild for 0.9.3 fron re2c.org The new version from http://re2c.org should compile cleanly.
Lisa seems to have commited the 0.9.3 ebuild three weeks ago, and it seems to compile cleanly on gcc 3.x (including 3.4.1 here). Closing then.
