I don't think there can be much argument that anything that Provides
c-compiler also has to make sure that standard header files like
<stdio.h> or <unistd.h> are present on the system. Otherwise it
wouln't be able to do its job, namely compiling C programs.
I have no a priori opinion about whether such making sure should
involve virtual packages, and if so which.
However, a -dev packages that contains C(++) headers is obviously only
useful if one already has a C compiler, so there should be no need to
depend directly on a libc-dev. One might argue that any -dev package
that provides a C interface should depend on c-compiler themselves,
but our traditional answer to that one seems to be, "don't be silly;
a user should be able to figure out *that* by himself".

I agree with this - it would need some compile-time parallel to shlibs
files in order to discover which possibly virtual package is the right
one to depend on to get /usr/include/foo.h.
However, for as long as we have to trace the dependencies by hand, I
see little benefit in requiring an explicit dependency on a libc-dev.
