# 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.
