# We unfortunately can't make a library for the common sources because
# making a library of C++ sources is not standardized.  :-( We also
# can't just list the same .cc files in multiple targets, because some
# C++ compilers will actually compile them multiple times (i.e., once
# for each target).  This results in a timestamp for wrap.o being
# later than already-finished targets (e.g., when wrap.o may end up
# with a timestamp before mpif77, but after mpicc).  So we have to sym
# link the common sources to unique names for each wrapper compiler
# and let them effectively be compiled once for each wrapper.

# Per bug 476, the "wipe" command is now "ompi_wipe".  So that we don't
# break backwards compatability, we provide sym link names to the old
# names (i.e., ompi_wipe -> wipe).  However, we provide a
# --disable-deprecated-executable-names option that will disable this
# behavior.  Someday, we'll change the default and the option will
# become --enable-deprecated-executable-names.
