Implement fpsetmask() and other fp*() functions. Programs should use #include <ieeefp.h> to access these functions instead of the i386 specific #include <machine/floatingpoint.h> Submitted by: Hidetoshi Shimokawa <simokawa@sat.t.u-tokyo.ac.jp>

/* $NetBSD: ieeefp.h,v 1.4 1998/01/09 08:03:43 perry Exp $ */
fp_except => fp_except_t for consistancy with the i386 and the tradition C methoid of nameing types.

o Move the contents of <machine/floatingpoint.h> over to <machine/ieeefp.h> where it belongs. o Remove the i386 specific inclusion of <machine/floatingpoint.h> from <ieeefp.h>, now that including <machine/ieeefp.h> is enough for all architectures. o Allow <machine/ieeefp.h> to inline the functions exposed by the headers by checking for _IEEEFP_INLINED_ in the MI header. When defined, prototypes are not given and it is assumed that the MD headers, when inlining only a subset of the functions provide prototypes for the functions not being inlined. Based on patch from: Terry Lambert <tlambert2@mindspring.com> Tested with: make release.

Breath deep and take __P out of the system include files. # This appears to not break X11, but I'm having problems compiling the # glide part of the server with or without this patch, so I can't tell # for sure.
