This solution seems awkward to me. There maybe not be a good pattern
that catch both a and b. Should gnu make have a more natural
solution to this problem?
I had the problem with ANTLR which is a parser-generator and generates
multiple files.
I ended up with a solution a la:
grammar.cpp: grammar.g
antlr …
lexer.cpp: grammar.cpp
touch $@
Here antlr generates both grammar.cpp + lexer.cpp, but as far as make
knows, lexer.cpp is generated from grammar.cpp which is what depends
on grammar.g.
