1024 & 4096, resp.

Thanks, I've set it to 2048 that way and that was enough to get past llvm.

Setting X to 1 in the JOBS=X setting for make-nsis-installer made no
difference.

That llvm issue must be a recent change as a mxe build tree freshly cloned
in January ran w/o trouble.

My Mageia 6 system didn't accept that, with that addition it never got past
the login screen, and with ridiculously high values for fn.file-max (65336)
"ulimit -n" stubbornly reported 1024.
Removing the fn.file-max line in /etc/sysctl.conf restored the login
process.
Anyway that's another issue, My immediate problem is solved.

Thanks all,

Philip
