Re: Change a flag for a specific file

Hello Sylvestre,

It would be helpful if you did not omit the name and date of the quoted
part (makes searching for context much easier), thanks.

The above should work fine.

Which Automake version do you use?  Does Makefile.in contain a line of
the form
  libfoo_la_DEPENDENCIES = libdummy-foo.la

generated by Automake?  It does for me, with 1.9.6 as well as 1.9b.
