Don't know, all I know from autogen is that it is not easy to build locally.

So far I never encountered any difficulties with it under linux.

I tried different settings, and it looks like the code that is
enabled for autogen >= 5.18, but apparently the 5.18 behaves
like the old version, so this is probably not a back-port of a
new feature.  My guess is that simply the version should be
checked for autogen >= 5.18.1 ?

Then I change it to "Before Mac OS X 10.8"

BTW: I noticed that the fix-rule misses the siglongjmp,
because the parameter is sigjmp_buf.

Do you want an updated patch with these changes?
