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.
Are you sure this actually works? 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.
