Multiple vars in AC_SUBST not considered

[Jan Engelhardt]

Hi,


I observed that with a configure.ac with

        AC_SUBST([libfoo_CXXFLAGS libfoo_LIBS])

automake 1.10 will not generate the required

        libfoo_CXXFLAGS = @libfoo_CXXFLAGS@
        libfoo_LIBS = @libfoo_LIBS@

in Makefile.in, but will do so once I write

        AC_SUBST([libfoo_CXXFLAGS])
        AC_SUBST([libfoo_LIBS])

I am not sure AC_SUBST([multiplevars]) are allowed, the autoconf info 
pages suggest it only takes one. They do seem to be replaced by 
configure/sed however, as explicitly adding 

        libfoo_CXXFLAGS = @libfoo_CXXFLAGS@

to Makefile.am also makes the problem go away.



thanks,
Jan
