[sldev] Issue for tonight's meeting VWR-729

[Argent Stonecutter]

Personally, I don't think stdio should have been made locale- 
sensitive, but rather a more flexible library possibly including  
locale-sensitive extensions of stdio calls like printf and scanf  
should have been created, but that's water under the bridge now.  
However, building on that thought...

I believe option 4 is the correct path: don't call stdio scanning and  
formatting routines for these operations, but incorporate a number  
parser and corresponding numeric formatting function that is  
independent of locale. This would not need to be a full replacement  
for *printf/*scanf, since it's unlikely that more than a fraction of  
*scanf functionality is being used. In particular, given control of  
the file format, exponential notation need never be handled.

David Gay's strtod() implementation, used by FreeBSD, is released  
under a current-BSD-equivalent license (and hence is completely  
license-compatible with GPL code as well as both Linden Labs  
licenses) and will produce a locale-independent strtod by compiling  
it without USE_LOCALE defined.
