Comment (by majoc-at-astro):

 Replying to [comment:7 ryandesign]:

 > Unfortunately this port's build system evidently doesn't know to exit
 when an error occurs. It would be nice if we could fix that.

 This I think is the most entertaining part of this: `${FC} -O other_args`
 -> `-O other_args` -> `O other_args` plus an instruction to Make to ignore
 the error-exit value.  It's actually two features of Make interacting to
 produce a bug, for which the only portable fix afaict is "don't do that".
 With `gmake`, I've used startup-time traps before now of the form:

 {{{
 ifeq "" "${FC}"
  $(error I see an empty FC value here)
 endif
 }}}

 .... which isn't entirely complete (checking for `${FC}` being all-
 whitespace is left as an exercise), and would have to be replicated for
 all other interesting variables.  I've no idea what the BSD-make version
 would be; and, erm, is there a cmake expert in the house?

 Hope this helps.
