@esr: I've said something like this several times, and you haven't
addressed it. Please do.
It's obvious to me that the right thing in this case, and as a general
facility, is to be able to detect (target of course) header files at the
equivalent of configure time. autoconf does this via AC_CHECK_HEADER,
which uses the target compiler to compile a program that basically only
has a #include. This has been standard practice for years, and widely
useful. One of the points of feature tests rather than #ifdef on an os
name is that the tests automatically extend to similar systems. I
realize you don't like aspects of autoconf, but this part was entirely
successful.
Surely scons must be able to do the equivalent of AC_CHECK_HEADER. It's
inconceivable that it's not a built-in feature. What's going on?
