94b6baf5 66# -Bexport to the linker when linking perl is important because it leaves
67# the interpreter internal symbols visible to the shared libs that will be
ef2d312d 68# loaded on demand (and will try to reference those symbols). The -u option
69# to drag 'sigaction' into the perl main program is to make sure it gets
70# defined for the posix shared library (for some reason sigaction is static,
71# rather than being defined in libc.so.1). The 88110compat option makes sure
72# the code will run on both 88100 and 88110 machines. The define is added to
73# trigger a work around for a compiler bug which shows up in pp.c.

d83aa01c 99WARNING: If you are using ksh to run the Configure script, you may find it
100failing in mysterious ways (such as failing to find library routines which
101are known to exist). Configure seems to push ksh beyond its limits
102sometimes. Try using env to strip unnecessary things out of the environment
103and run Configure with /sbin/sh. That sometimes seems to produce more
104accurate results.
