[Users] CarpetMask compilation errors

[Erik Schnetter]

C++ compilers differ in their ways in which they make C functions such
as isnan available. There is a standard way, but there are often also
additional "backward compatible" ways, and this can sometimes lead to
confusion. In your case, the C++ compiler sees two "different"
versions of isnan and thus reports an error.

We have determined compiler options and header flags that make things
work for almost all standard operating systems and standard compilers.
We have documented these in the simulation factory
<http://simfactory.org>, which can also be directly accessed at
<https://svn.cct.lsu.edu/repos/numrel/simfactory/branches/PYSIM_DEV/mdb/optionlists/>.

What machine, operating system, and compiler are you using? Your best
bet is probably to start with the options for a machine most closely
to your setup.
