# Test remake rules when an m4 file gets removed and the macros it
# defined get inlined into the caller.  Try with both an indirect
# call and a direct one.  This can be seen as testing the "deleted
# header file" issue w.r.t. aclocal.m4 dependencies.  See also
# related test 'aclocal-deleted-header.sh'.
