I have been working on writing tests for default_target_compile,
initially with a goal to rewrite default_target_compile, but now I have
added another goal: documenting default_target_compile, since the
existing entry in the manual is a stub.
I have gathered lists of recognized types and options from the code and
am now perplexed at what type "none" is actually supposed to do -- the
current implementation ends up invoking the compiler with no specified
mode or output, which produces a.out as an executable here.
I understand allowing no output file with "preprocess" -- GCC emits the
preprocessed output on stdout, which becomes the return value of
default_target_compile. But what is type "none" supposed to do?
