I'll work on posting an example.
We do not use @x@ to expand subdir lists; that forces too much info into
configure.XX.
We write either:
if FOO
SUBDIRS = a b c
endif
or
if FOO
X_DIRS = a b
endif
SUBDIRS = $(X_DIRS) d e
Again, I'm not sure why automake cares about SUBDIRS. From the .texi:
Although the @code{SUBDIRS} macro can contain configure substitutions
(e.g. @samp{@@DIRS@@}); Automake itself does not actually examine the
contents of this variable.
