# The two flags "-fpic -DPIC" are used to indicate a
# will-be-shared object. Configure will guess the -fpic, (and the
# -DPIC is not used by perl proper) but the full define is included to
# be consistent with the FreeBSD general shared libs building process.
#
# setreuid and friends are inherently broken in all versions of FreeBSD
# before 2.1-current (before approx date 4/15/95). It is fixed in 2.0.5
# and what-will-be-2.1

Some users have reported that Configure halts when testing for
the O_NONBLOCK symbol with a syntax error. This is apparently a
sh error. Rerunning Configure with ksh apparently fixes the
problem. Try
ksh Configure [your options]
EOM
if [ "X$usethreads" != "X" ]; then
if [ ! -r /usr/lib/libc_r.a ]; then
cat <<'EOM'
The re-entrant C library /usr/lib/libc_r.a does not exist; cannot build
threaded Perl. Consider upgrading to a newer FreeBSD snapshot or release:
at least the FreeBSD 3.0-971225-SNAP is known to have the libc_r.a.
