The main 64bit issue that I am aware of with libltdl (1.5.x and HEAD)
is the casting between void* and function pointers, which is not
strictly allowed by the standards. If you have any other specific
examples I would be pleased to hear about them...
Once we have the next round of releases, I will start to look at the
function pointer casting problem right away. Patches gratefully
received in the meanwhile -- it does unfortunately involve some deep
work in the internal calls of libltdl.
Cheers,
Gary.
