#961 new enhancement

Add an option for enabling floating point exceptions

Description

Cactus disables floating point exceptions, so that NaNs and Infs can be generated by numerical code. When debugging, it is sometimes very helpful to use these exceptions, as a debugger will tell you exactly which piece of code generates them.

I propose that Cactus should have a run-time parameter, defaulting to "no", which enables floating point exceptions.

Thorn TAT/NaNCatchers does this (for x86 architectures). It is available from <https://svn.cactuscode.org/projects/TAT/NaNCatcher>.
