Thanks.  As far as I can see, this error is happening because the open
system call failed and set errno to some value.  When strerror was
called on that value, it returned "File name too long".  Presumably
the errno value is ENAMETOOLONG.

You might try running gcc with the -v option to see what the last
directory in the search path is, since it is presumably when using
that directory that ENAMETOOLONG is returned.

Otherwise I don't have any suggestions other than running it in the
debugger to see what the actual failing name is.
