Re: 1.11 doesn't add sources with nonstandard suffixes when making a binary

[Юрий Пухальский]

Automake links binaries through libtool too, at least in my case.

And yes, it works when i make a rule from .pc to .c, but:
How do i clean the intermediate .c file in this case?
I must add BUILT_SOURCES everywhere, use EXTRA_DIST for distributing
the original files.
Generally it's less clear than specifying .pc file directly in _SOURCES.

As for silliness, it's exactly as silly as default .l.o implicit rule
in standard make:
.l.o:
    $(LEX) $(LFLAGS) $<
    $(CC) $(CFLAGS) -c lex.yy.c
    rm -f lex.yy.c
    mv lex.yy.o $@
