I'd like to address the C locale dependency of fromfile and fromstring. 
(setlocale() affects fromfile, but does not affect fromstring; locale can 
make eg. "," become the decimal separator instead of ".").

I'd assume we want to follow Fortran and Python here, and *not* format or 
parse floating point numbers according the C locale. Use of fscanf might 
need to be reconsidered, or the calls need to be wrapped in setlocale
("C"); setlocale(old_locale); pairs...

Locale-related tickets: #884, #902, #695

Running numpy tests under different locales and calling
setlocale(LC_ALL, "") may reveal some additional points to address.
