I'm working on a fairly large project, and in an effort to be moderately organized, I'm placing every class, every part, in a seperate .cpp/.h pair. Needless to say, since each part needs several of the others, this leads to a large amount of #Include's.
I've had no problems with this, until today, when modifying one specific part required the adding of a couple more #includes. Now, I'm suddenly getting a bunch of the following errors:

warning C4182: #include nesting level is 362 deep; possible infinite recursion

and

fatal error C1076: compiler limit : internal heap limit reached; use /Zm to specify a higher limit

Is there a limit to the number of #includes that can be used in any given project? What is this internal heap limit, and is this /Zm?
