Update of /b/source/CVS/src/sys/arch/i386/include
In directory sun-lamp.cs.berkeley.edu:/c/users/jtc/i386/include

Modified Files:
	npx.h 
Log Message:
FPU control word of 0x137f doesn't work well in "real" world applications
so I've changed it to 0x127f.  64 bit precision causes errors in paranoia
and our math library, changing to 53 bit precision solves these problems.

I've been told that long double support in Gcc 2.5 requires 64 bit mode,
so a comprehensive FP strategy (compiler, library, FPU, emulator) will
have to be addressed in the future.
