Re: symbolic links, unreadable files, skip

Because a dead symbolic link has no substance. Even if it's ignored,

nothing is lost. (Stat(1) is used for detecting a dead symbolic link.)

Unlike that, an unreadable file means that something critical has 

occurred. In that case, gtags stop its job, and give the user a chance 

to check the disk, permission and etc.

Sure, test if fopen fails. :)

Yeah, that's what I meant.

Plug-in parsers can do what they want, that's not the issue.

You ignore files when stat fails, why not ignore files when
fopen fails?  That's what the attached patch does.  Oh, I
was also able to successfully use skip on the broken link,
so I don't know what went wrong there.
