There are likely many places in GDAL where we unfortunately use locale 
sensitive rountines and we shouldn't. You can workaround this at your side by 
including cpl_conv.h and adding a "CPLLocaleC oLocaleCForcer;" before calling 
GDAL code. This will switch to the C locale temporarily and restore the 
original locale afterwards (at the end of the block where the object is 
declared).
