[Ipopt] Random number generator compilation error

[Jason Moore]

I just realized this solution did not go to the list.

Also, a private email was sent to me with this suggestion:

"I have today the same error but I do this and works:
run configure with this argument
coin_skip_warn_cxxflags=yes"

Which I have not tested.
