Sometimes when I reconfigure libgcj, configure decides that mmap doesn't work on my machine. This breaks the .db feature. I don't know exactly how to reproduce, but I have seen it more than once.
Confirmed.
I'm testing a fix.

I checked in the fix on the trunk.

Tom, what am I doing wrong? I seem Mike Stump checking in these kinds of cleanup of reconfigured files as well. Currently I'm using mainline/gcc-4_0 autoconf 2.59 automake 1.9.3 gcc-3_4-branch autoconf 2.59 automake 1.7.8 and reconfiguring with "autoreconf" Are these not the right tools, or what's up? thanks, benjamin
The versions you're using all look right. In this case I regenerated configure and whatnot due to a change in config/. I haven't been using autoreconf though; I've been running the tools by hand, looking in Makefile.am to see what args to use for aclocal.
