 HEADERS should be used for all .h files as well as .c files that are
 conditionally compiled (eg LIBOBJS)

+Defined variables, their meanings, and their effects:
+
+DEFS           cpp definitions
+INCLUDES       -I options to cpp
+CPPFLAGS       more cpp flags
+CFLAGS         flags to cc
+SOURCES        any sources (do not use?)
+CONFIG_HEADER  path to config.h
+SUBDIRS        subdirectories to build in.  means this is a "top level"
+               directory.
+PROGRAMS       list of programs to build.  sources for program `foo' are
+               in foo_SOURCES.  objects are auto-build.  (only put .c
+               files in foo_SOURCES)
+LIBPROGRAMS    programs to build and install in libexec
+SCRIPTS        programs which are actually scripts (architecture
+               independent)
+LIBSCRIPTS     scripts to build and install in lib
+LIBRARIES      libraries to build.  sources for library `foo' are
+               in foo_SOURCES.  Only put .c file name in that variable.
+TEXINFOS       texinfo files to build.  must end in ".texi"
+MANS           man pages to install
+ALLPROGRAMS    like PROGRAMS, but used at build time.  define this if
+               the programs you want to build are determined by configure.
+
+If your Makefile.am includes "@kr@", then ansi->kr conversion is
+assumed.
