kleink b3f30828b1 Document isinff(3) and isnanf(3), cloned from the corresponding double-
precision manual page.  It is kept separately since the latter are part of
libc and thus impose different linkage instructions.

kleink 9ef6f05359 G/C this copy of <math.h> in favor of the version found in basesrc/include,
which is actually the one installed.  The latter (which is derived from this
file) has evolved since, and the argument that it is exlusively associated
with libm (and thus should be installed from this directory) no longer holds
since two interfaces (isinf() and isnan()) are part of libc these days.

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