Hello,

While looking though ltmain source code i've stumbled upon this egrep
invocation:
$EGREP ' (_head_[A-Za-z0-9_]+_[ad]l*|[A-Za-z0-9_]+_[ad]l*_iname)$'
I've tried to see how it behaves on some import libraries that i have, and it
turned out that i could never get it to detect the iname lines, unless i escape
the plus sign.
May be I misunderstand issue.
$ echo ' _head_ABC_a' | egrep ' _head_[A-Za-z0-9_]+_[ad]l*$'
_head_ABC_a
$ echo ' _head_ABC_al' | egrep ' _head_[A-Za-z0-9_]+_[ad]l*$'
_head_ABC_al
but:
$ echo ' _head__al' | egrep ' _head_[A-Za-z0-9_]+_[ad]l*$'
$ echo ' __head_ABC_al' | egrep ' _head_[A-Za-z0-9_]+_[ad]l*$'
$ echo ' _head_ABC_zl' | egrep ' _head_[A-Za-z0-9_]+_[ad]l*$'
Are you sure this actually works?
I'm not expert in regular expressions but according above tests "plus"
in RE works - see case _head__al .
Note that the function that does this is only
used in rather exotic corner-cases (old dlltool and/or ms dumpbin being in
use), so it's plausible that it could have been broken since 2010, when it was
added.
