I stopped using my middle name years ago.

Convert files to UTF-8 and add some copyright markers where missing.

Better safe than clever.

- fabsl.c should be named s_fabsl.c for consistency with libmsun's
documented naming scheme (unfortunately the documentation isn't in the
tree as far as I can tell); no repocopy is required as there is no
history to preserve.

- replace simple and almost-correct implementation with slightly hackish
but definitely correct implementation (tested on i386, alpha, sparc64)
which requires pulling in fpmath.h and the MD _fpmath.h from libc.

- try not to make a mess of the Makefile in the process.

- enterprising minds are encouraged to implement more C99 long double
functions.
