Dependency of Makefile.in is not awared of

[Tzu-Chien Chiu]

Hello all.

I have a strange problem on cygwin. The Makefile generated by
'configure' doesn't detect the change of Makefile.am. I have to
manually remove the corresponding Makefile.in to force it to be
re-generated.

Examing generated Makefile I found the dependency of Makefile.in are
commented out by #. Is it on purpose? Or I missing anything in
configure.ac?


.SUFFIXES:
am--refresh:
       @:
$(srcdir)/Makefile.in: # $(srcdir)/Makefile.am  $(am__configure_deps)
       @for dep in $?; do \
         case '$(am__configure_deps)' in \
           *$$dep*) \
             echo ' cd $(srcdir) && $(AUTOMAKE) --foreign '; \
             cd $(srcdir) && $(AUTOMAKE) --foreign  \
               && exit 0; \
             exit 1;; \
         esac; \
       done; \
       echo ' cd $(top_srcdir) && $(AUTOMAKE) --foreign  Makefile'; \
       cd $(top_srcdir) && \
         $(AUTOMAKE) --foreign  Makefile


The versions of the programs I use:
* autoconf 2.59
* automake 1.9.6
