Thanks for the patches. Unfortunately, I have two problems with them :
1) The m4-files are GNU licensed, YXA is BSD licensed. I'm quite
ignorant regarding OSS licensing, and have to be convinced (not
necessarily by you) that it is not a bad idea to include these files.
2) It doesn't work out of the (my) box. I get errors which I've tried to
sort out but m4/autoconf makes my head spin. Any help would be
appreciated.
YXA trunk, clean check out. Only patch 1/2 applied (also tried with
both). This is on Ubuntu Jaunty, which has autoconf 2.63-2ubuntu1.
