A well written configure script is able to detect presence
of a linkable libcurl.
IMO the reasons configure is so unwieldy, at least as it's set up in
most open source projects, are that a) it spends 95% of its time
checking for things that basically never vary (yes, I have stdlib.h,
thank you) and that b) it doesn't remember the results from previous
runs on the same host (I'm just changing the install path; my ints won't
have stopped being 32 bits as a result.) I wonder if we could satisfy
most people with a configure script -- maybe not based on autoconf --
that is limited in scope to just the things that are currently tweakable
in the git Makefile.
If configure ran only, say, 10-15 tests, I bet the fork+exec overhead on
Cygwin would be perfectly tolerable.
