Ah. The former sounds sensible from here.
This kind of points up that I've always thought the advice at the top of
configure.in is a tad broken:
dnl 0. Initialization and options processing
dnl 1. Programs
dnl 2. Libraries
dnl 3. Header files
dnl 4. Types
dnl 5. Structures
dnl 6. Compiler characteristics
dnl 7. Functions, global variables
dnl 8. System services
Why isn't "Compiler characteristics" a lot earlier in the list, certainly
before "Libraries"?
