[Wesnoth-dev] locale-independant number parsing

[Yann Dirson]

Looking around a bit, I found that glibc provides a set of functions
to specify in which language we want the number to be parsed.

So instead of using atof() we can use strtof_l() if available.

No objection to check for the availability of this function, and only
if not, then revert to the setlocale()-based workaround ?

Was there any specific reason to use atoxx() rather than strtoxx(),
appart for them to be more concise ?  I note that there are indeed a
couple of calls to strtoul(), so I guess it is not a portability
issue.  Consistently using strto*_l(), #defined to their standard
strto*() counterparts when not available, would provide an easy way to
handle this.

What do you think ?
