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.

217POSIX threads are not supported well by FreeBSD $osvers.
218
219Please consider upgrading to at least FreeBSD 2.2.8,
220or preferably to the most recent -RELEASE or -STABLE
221version (see http://www.freebsd.org/releases/).
222
223(While 2.2.7 does have pthreads, it has some problems
224 with the combination of threads and pipes and therefore
225 many Perl tests will either hang or fail.)
