So, I cannot reproduce. => Next time, please tell how to reproduce it.

​Current master head of https://github.com/rrthomas/enchant/ :

./autogen.sh

make

make clean

make distclean​

2) When I look at the generated Makefile, I see this snippet:

        case "$@" in \
          distclean-* | maintainer-clean-*) list='$(DIST_SUBDIRS)' ;; \
          *) list='$(SUBDIRS)' ;; \
        esac; \
        for subdir in $$list; do \

Have you tried to define the DIST_SUBDIRS variable in Makefile.am [1], listing the
subdirectories in reverse order?

​I tried this just now, and it merely shifts the problem to lib/, where I get

make[1]: Entering directory '/home/rrt/.local/var/repo/enchant/lib'
Makefile:861: .deps/alloca.Plo: No such file or directory
Makefile:862: .deps/alloca.Plo: No such file or directory

Makefile:869: .deps/unistd.Plo: No such file or directory
make[1]: *** No rule to make target '.deps/unistd.Plo'. Stop.

This is because when running "make distclean" in src it does:

rm -rf ../lib/.deps ./.deps

Looking at automake's source, this is a result of removing DEPDIRS, which is a pseudo-variable (defined specially in the automake script), which expands to the list of directories from @deplist.

I cannot see how relocatable.c is treated specially (i.e. included directly, as it needs to be, rather than just via libgnu.la). m4/relocatable-lib.m4 doesn't seem to mention it, and modules/relocatable-lib-lgpl doesn't seem to do anything special with the relocatable.[ch] files, just mentions them as deps.
