Yes. There exists lstat in gnulib but configury #ifdef would be more
appropriate here I think.

Still you call there:
+ dir1 = xstrdup (objfile->name);
+ canon_dir = lrealpath (dir1);
and later:
+ dir2 = lrealpath (objfile->name);
For all the directory components of objfile->name lrealpath will lstat them by
syscalls twice (for NFS it may get hopefully cached, not sure). There were
some complaints on GDB slowness on NFS.
I do not require this optimization, there are still worse issues on NFS.
Thanks,
Jan
