Consider automake being used together with GNU make and autoconf.
Top level directory 'main'. Two subdirectories, 'a' and 'b'. main/configure.ac AC_CONFIGFILES([ ... a/somefile.inc ... ]) main/Makefile.am: SUBDIRS=a b main/a/Makefile.am: data_DATA=somefile.inc DISTCLEAN=somefile.inc main/b/Makefile.am include $(shell pwd)/../a/somefile.incmain's configure creates a/somefile.inc frome somefile.inc.in, and main/b/Makefile will include it, since automake will refuse to parse such an include file, and leave it up to make to deal with. somefile.inc also gets installed (yes, I'm installing a makefile fragment, this is a development tool); and it also needs to be DISTCLEANed, for make distcheck to pass.
However, what's going to happen here is that distclean-recursive ends up recursing into main/a first, and remove somefile.inc, and failing when it subsequently recurses into main/b, since the included file isn't there any more.
I think that distclean-recursive should handle SUBDIRS or DIST_SUBDIRS in reverse order from what they're listed. Or, default to SUBDIRS in reverse order, or the explicit order given in DIST_SUBDIRS. In the meantime, off I go writing another convoluted gmake macro to set DIST_SUBDIRS by reversing SUBDIRS…
