# The VMS POSIX `c89' command writes any/all diagnostic info to stdout
# rather than stderr, confusing configure tests which capture error output.
#
# Also, the VMS linker issues a warning for any undefined symbol, but that
# does not inhibit creation of the final executable file, again confusing
# configure. As an added complication, there's not enough control of the
# linker to put the map file with chosen name into the current directory.
