But with m4, you can arrange for AM_INIT_AUTOMAKE to redefine AC_PROG_CC
so that it hooks in a call to AM_PROG_CC_C_O immediately after its
current definition, and thus still preserve desired ordering while
making the burden simpler for the configure.ac author.

How much speed penalty and configure bloat are we talking about by
allowing projects to omit the use of this macro if they don't care about
inferior compilers?  Is anyone really going to complain if we switch to
always supporting inferior compilers?
