The source tree in the below build is under /tmp/gcc-4.2.1--x---x----x/. Note
how the path contains 1, then 2, then 3, then 4 hyphens.

Makeinfo is looking for at-file.texi under an incorrect source path: each run
of two or more hyphens in the path is shortened by one. I believe this is due
to Texinfo's typographic syntax conventions being incorrectly applied to the
@value{srcdir} substitution in invoke.texi.
