I don't really understand what exactly is the problem with MSC, so I
cannot give any definitive answer.

DJGPP allows you to control the FPU behavior by providing a function
to set the x87 control word.  For example, setting a certain bit there
would cause SIGFPE to be delivered to your program if you try to
compute exp(MAX_INT).

If you ask whether GCC emits instructions which change the x87 status
word, then I don't think it does, at least in simple programs that I
tried.
