Bug in detecting GNU ld

[Luke Bakken]

Hello,

I believe I have discovered a bug in how libtool detects GNU ld (and
perhaps other GNU programs, like nm).

Here is a typical detection conditional:

if $LD -v 2>&1 </dev/null | egrep '(GNU|with BFD)' 1>&5; then
  lt_cv_prog_gnu_ld=yes
else
  lt_cv_prog_gnu_ld=no
fi


Notice that the statement $LD -v 2>&1 </dev/null | egrep '(GNU|with BFD)'
will return 0 if the egrep succeeds, and that this represents 'false' to
the if statement.  If GNU ld is on the system, then it will not be
detected correctly!!!

To fix this, I have swapped the 'yes' and 'no' where this situation
occurs - an alternative is to place a ! after the if and before the
commands.

I have attached the output of the following statement in hopes of tracking
down all of these problems:

address@hidden ~/libtool-1.4.2
$ grep -r -A5 -B5 'BFD' * > ../bfd.err 2>&1

If I can be of any assistance, please let me know.

Thanks,
Luke Bakken
