-build ldexp/frexp/modf locally again rather than relying on libc
 reaching over, to get things into a sane state,
-do the usual namespace protection game with scalbn(f) because it
 is used internally
(more symbol renamings are necessary)

The weak_alias change for mc68881 is untested.

-fix a long-standing bug which affects the <close-to-1>^<huge number> case
 (fixed in fdlibm-5.3)
-being here, sync with -5.3 as far as possible (There is another bugfix -
 sign in overflow/underflow cases -; this doesn't change anything for us
 because the wrapper (w_pow.c) fixes this up. Keep things in sync anyway
 to ease further maintainance.)

Changed core routines to call __ieee754_sqrt() instead of sqrt().  I
reported this enhancement to fdlibm-comments, and got the following

You are right. __ieee754_sqrt should be in use with e_*.c.

LIBM_SCCS must be defined for the RCS ID to be defined.
This library will soon be used by DJGPP.  And since memory is often tight
on DOS machines, there is little benifit to be had from including RCS IDs.
