Only if you're happy with the licensing terms of gnulib, which often are 
GPL -- or possibly LGPL (the gnulib strtod module is LGPL).  Depending 
on legal advice, sometimes not even LGPL is acceptable (my employer bans 
the use of LGPL libraries, unless dynamically linked.  For gnulib, it's 
always a static link, so no-go).

Mingw(-runtime) provides viral free implementations of (certain) 
functions in libmingwex, for precisely these reasons.  And the purpose 
of libmingwex itself is to improve C99 compliance of the mingw compile 
system -- not tell users "go use this [L]GPL module from this other 
library".

Don't get me wrong, I'm a fan of copyleft. But avoiding copyleft seems 
to be a theme for mingw and the related runtimes, for several good reasons.
