I'll speak out loudly clearly:

curl and libcurl do not support file transfers larger than 2GB today. You can
still do it if you're using chunked HTTP transfers, but for all other
transfers you need to fix the problems in the curl and libcurl source code.

Those are zlib functions.

This is a problem I happened to introduce in 7.10.6 because I accidentally
included the wrong version of scr/hugehelp.c in the distribution archive (this
version is compressed and requires zlib to uncompress). You can remove it, and
it should be regenerated fine by the makefile and then it should not require
zlib anymore...

Nope. There's no such option to curl's configure. And as you showed us,
configure detected that the compiler doesn't need any extra options to support
large files.

curl is useless without libcurl, as libcurl does all the file transfering.
Thus, the 2GB problem is not really a curl problem, it is a libcurl problem
and as such it is highly relevant for you.
