4 # Boyd Gerber, gerberb@zenez.com 1999/09/21 for threads support.

20 # More optimisation provided in gcc-2.95 causes miniperl to segv.
21 # -fno-strict-aliasing is supposed to correct this but
22 # if it doesn't and you get segv when the build runs miniperl then
23 # disable optimisation as below

34 # Our default setup excludes anything from /usr/ucblib (and consequently dbm)
35 # as later modules assume symbols found are available in shared libs
36 # On svr5 these are static archives which causes problems for
37 # dynamic modules loaded later (and ucblib is a bad dream anyway)
39 # However there is a dbm library built from the ucb sources outside ucblib
40 # at http://www.sco.com/skunkware (installing into /usr/local) so if we
41 # detect this we'll use it. You can change the default
42 # (to allow ucblib and its dbm or disallowing non ucb dbm) by
43 # changing 'want_*' config values below to '' to disable or otherwise to enable

211 If you wish to use dynamic linking, you must use
212 LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH
214 setenv LD_LIBRARY_PATH `pwd`
217 If you are using shared libraries from /usr/local/lib
218 for libdbm or libgdbm you may need to set
219 LD_RUN_PATH=/usr/local/lib; export LD_RUN_PATH
220 in order for Configure to compile the simple test program
