libm performance

Consider the example of glibc for x86; the <mathinline.h> has been in use
for some time, and the linkable functions are written in .s.  No one has
seen fit to correct bugs such as those which limit the accuracy of the long
double versions, or produce un-warranted NaN's in limiting cases.  Yet, you
are free to supply your own <mathinline.h> or link any of your own function
versions before linking against the library, so that you may easily take
responsibility yourself for the performance of your libm.
