pynac fails to build (sage 9.4.beta4, clang)

[Vincent Delecroix]

Dear all,

I am not able to build pynac with clang because of the error

error: no member named 'numeric_limits' in namespace 'std'

See attached log for details.

Best
Vincent

Should be solved by the move to penal-0.7.29. This is the same kind of errors that I fixed for g++11.

I'm pretty sure you typed pynac-0.7.29 and some automatic

let-me-assume-you-wanted-to-type-something-else engine

changed that to whatever was sent to the mailing list.  : )

With some effort these engines can actually be turned off.

Yeah, I turned it off on a previous machine after a funny replacement of lapack.

Using clang is untested. 

Please help with https://trac.sagemath.org/ticket/30835, which sets up testing infrastructure for system configuration variants using clang.
