<smaller>It turns out that we are passing a string containing a number
with a trailing space.  The 1.32.0 version of lexical_cast did not
mind the trailing space, but the 1.33.0 version throws a
bad_lexical_cast exception.  I found that if I change this:</smaller>

<smaller>that my issue goes away, but the workaround for compilers
without the eof() function still works....  Would it be possilbe to
add this into 1.34.0, or is this undesirable behavior?</smaller>

This looks like a reasonably change to me; I hope that someone more
involved in lexical_cast<<> can give us more information, either
rationale for the 1.33.0 behavior or confirmation that this is a bug.
If it is a change that needs to be made, we'll put it in 1.33.1.
