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

31# setreuid and friends are inherently broken in all versions of FreeBSD
32# before 2.1-current (before approx date 4/15/95). It is fixed in 2.0.5
33# and what-will-be-2.1

113Some users have reported that Configure halts when testing for
114the O_NONBLOCK symbol with a syntax error. This is apparently a
115sh error. Rerunning Configure with ksh apparently fixes the
116problem. Try
117 ksh Configure [your options]
