QuickC stuff

On compiling my code with Microsoft Quick C 2.?, I put in the /FPi87
flag in the make file. I'm not sure whether QuickC actually recognizes
this flag. Also, in looking at the assembly code generated, I noticed that
it does not generate 8087 instructions. What it actually does is generate
code to call some math emulator functions via interrupts, but I want to
run this code within an Interrupt Service Routine without goofing around
with calling other interrupt functions.
In looking at the code with CV, I found something of the following:
int 37 ;fild dword ptr [FFfac (2009)]
int 3d ;fwait
les bx,dword ptr [p_temp]
int 3c ;fstp dword ptr es:[bx]
int 3d ;fwait
If it amounts to actually going into the assembly code and changing
the assembly code so that the 8087 is used, then I will. But not if
there's something that I have missed.
Could anyone give me a clue as to what, if any, compiler flag will actually
put in 8087 in-line code (for real!) using QuickC?
Thanks
