Wise? Not necessarily.

Sorry, but none of that makes a lot of sense. Why can't you just put libcurl
in a separate directory and build that first exactly the way you want it, then
you build your app and link (statically) with the libcurl you just built. Then
you're not dependant on any mismatches, bad platforms, weird distributions or
anything. You have the full power to set it up exactly as you like it.
The bonus is that you're then building libcurl as it was made to get built so
you don't get a lot of extra head aches because of special requirements and

I'm not at all convinced that's a particularly good idea for your average
library. I can't see any particular benefits for us to have libcurl optmized
for such a use.

Don't read the Makefile, read Makefile.am. Just build all lib/*.c files.

It includes its own headers so the macros and defines are there. Did you
forget to run configure first?
