lex & yacc with C++ projects

[Robert Collins]

It would be nice to be able to tell automake that we want to compile the
out of lex and yaxx with g++, not gcc. (this is for C++ projects).

Is there any way to do this currently?

At the moment I've got the .cc files listed as BUILT_SOURCES, and custom
rules to make them. This isn't very satisfactory, as depcomp doesn't
then operate (or I copy the exact rule from Makefile.in and get tightly
bound to a version of automake...)
