At start, I began on my own, without any howto, but as I couldn't get
compilation working I tried to find some help. Thank for your advice, I
will try crosstool, and ask further questions on crossgcc list.

According to the error message, this is a good question. But bison and
byacc are installed... however, the configure script doesn't say clearly
if bison is present or not according to its tests.

Good question :-) I just did my latest test with them to try to
understand compilation problems. But of course, I should use
TARGET=i686-pc-openbsd3.7
Thanks for all.
