8# For consistency with gcc, we do not adopt Sun Marketing's
9# removal of the '2.' prefix from the Solaris version number.
10# (Configure tries to detect an old fixincludes and needs
11# this information.)
12
13# If perl fails tests that involve dynamic loading of extensions, and
14# you are using gcc, be sure that you are NOT using GNU as and ld.  One
15# way to do that is to invoke Configure with
16#
17#     sh Configure -Dcc='gcc -B/usr/ccs/bin/'
18#
19#  (Note that the trailing slash is *required*.)
20#  gcc will occasionally emit warnings about "unused prefix", but
