# (Configure tries to detect an old fixincludes and needs
# this information.)

# If perl fails tests that involve dynamic loading of extensions, and

# way to do that is to invoke Configure with
#
#     sh Configure -Dcc='gcc -B/usr/ccs/bin/'

# If the C compiler is gcc:

#	(GNU as and ld 2.8.1 and later are reportedly ok, however.)
# If the C compiler is not gcc:

#	(GNU as and ld 2.8.1 and later are reportedly ok, however.)

# Watch out in case they have not set $cc.

# Perl compiled with some combinations of GNU as and ld may not
# be able to perform dynamic loading of extensions.  If you have a
