[Ipopt] Memory Limit

[Mostafa.B]

Tony,
Actually I am using Pyomo to build my problems, as far as I know, pyomo
builds .nl files and passes it to IPOPT using the ASL thing.
I am using MinGW 64 bit, I got the trunk version a few days ago, don't know
the exact date but definitely it was between 15 to 22 of April.
