Have you done much porting of open source to z/OS?
I don't actually know if the libssh2 upstream can be configured for z/OS
(#ifdef __MVS__).
It is often a challenge, since:
- the shell is a "posix" ksh variant,
- make isn't gmake,
- the compiler isn't gcc,
- the library isn't libc,
- the system codepage is EBCDIC (IBM-1047),
- etc, etc, etc.
Rocket Software (a vendor of lots of z/OS software) has ported lots of open
source tools, including libssh2 that they make available for free (and sell
support).

It looks like they currently have 1.4.3, but you might at least start there.
