# Internally at Concurrent, we use a source management tool which winds up
# giving us read-only copies of source trees that are mostly symbolic links.
# That upsets the perl build process when it tries to edit opcode.h and
# embed.h or touch perly.c or perly.h, so turn those files into "real" files
# when Configure runs. (If you already have "real" source files, this won't
# do anything).

# Need to use Concurrent cc for most of these options to be meaningful (if

# -Bexport to the linker when linking perl is important because it leaves
# the interpreter internal symbols visible to the shared libs that will be
# loaded on demand (and will try to reference those symbols). The -u option
# to drag 'sigaction' into the perl main program is to make sure it gets
# defined for the posix shared library (for some reason sigaction is static,
# rather than being defined in libc.so.1). The 88110compat option makes sure
# the code will run on both 88100 and 88110 machines.

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