libstdc++ configure foobar ?

- Subject: libstdc++ configure foobar ?
- Reply-to: espie at nerim dot net
I've been trying to commit needed configure/configure.in changes to
libstdc++, but I can't.
The configure and configure.in files in libstdc++ are out of synch,
both in HEAD and in the 3.1 branch.
What's up ? Am I supposed to just commit to configure.in, or just blindly
re-generate configure with autoconf-2.13 and hope for the best ?
Specifically, configure regeneration yields the following diff, on the 3.1
branch...
Considering that what I want to merge is precisely an header file test,
I'm a bit wary...
