I don't have a solution to the ordering problem either, but it is possible with GNU ld's --version-script option on ELF platforms to control what gets exported in a fashion somewhat similar to what the VMS linker options file does. If a symbol isn't in the list you supply with a global tag, it doesn't get exported in the dynamic library, so you'd find out right away if there is anything that needs to be declared CURL_EXTERN that isn't.

Unfortunately I don't think there is any way to do this across compilers and platforms, but it can be one way to wrangle the symbols such that only those that should be exported are.
