30# The two flags "-fpic -DPIC" are used to indicate a
31# will-be-shared object. Configure will guess the -fpic, (and the
32# -DPIC is not used by perl proper) but the full define is included to
33# be consistent with the FreeBSD general shared libs building process.

35# setreuid and friends are inherently broken in all versions of FreeBSD
36# before 2.1-current (before approx date 4/15/95). It is fixed in 2.0.5

160the O_NONBLOCK symbol with a syntax error. This is apparently a
