One place this would come in handy is for CPPFLAGS in situations when MacPorts'
default "`-I${prefix}/include`" is problematic for some build systems. Ideally
the build systems should be fixed of course, but when that's difficult, some
ports (like abiword) may write "`configure.cppflags -I. -I${prefix}/include`";
with this patch to base, it could be more simply written
"`configure.cppflags-prepend -I.`".
But another way to handle that issue is to replace "`-I${prefix}/include`" with
"`-isystem${prefix}/include`", and several ports (like freetype, ghostscript
and pianobar) do that. Which brings up the question of whether we should change
MacPorts' default configure.cppflags to that. Would there be any harm?
