[jna-users] libc loading on solaris

[Timothy Wall]

You might try pulling down the official standalone libffi sources to  
see if those build properly without mods.  The JNA version has a few  
local mods and was last pulled from a tagged GCC release.  The JNA  
patches haven't yet been applied to the standalone libffi, and there  
have been some changes to standalone libffi that haven't been rolled  
into the JNA version.
