%b substitute the basename of the input file being processed.
This is the substring up to (and not including) the last period
and not including the directory.
+ %B same as %b, but include the file suffix (text after the last period).
%gSUFFIX
substitute a file name that has suffix SUFFIX and is chosen
once per compilation, and mark the argument a la %d. To reduce
specified to CC. Note that the tail part of the -S option
(i.e. the part matched by the `*') will be substituted for each
occurrence of %* within X.
+ %{<S} remove all occurences of S from the command line.
+ Note - this option is position dependent. % commands in the
+ spec string before this option will see S, % commands in the
+ spec string after this option will not.
%{S:X} substitutes X, but only if the -S switch was given to CC.
%{!S:X} substitutes X, but only if the -S switch was NOT given to CC.
%{|S:X} like %{S:X}, but if no S switch, substitute `-'.
