subdir-objects and generated file names

[Vincent Torri]

Hey

I'm porting a lib to a non recursive make build system. I have a
single top level Makefile.am which has:

AUTOMAKE_OPTIONS = subdir-objects

include src/lib/css/Makefile.mk

In that Makefile.mk, yacc is called and generates the file
src_lib_css_libecss_la-ecss_grammar.h from ecss_grammar.y (both of
them are in src/lib/css)

is it possible to keep the name grammar.h and not
src_lib_css_libecss_la-ecss_grammar.h while using the subdir-objects
option ?

thank you
