/*
WARNING: the implementation of the wxStrtoX_l() functions below is unsafe
in a multi-threaded environment as we temporary change the locale
and if in the meanwhile an other thread performs some locale-dependent
operation, it may get unexpected results...
However this is the best we can do without reinventing the wheel in the
case !wxHAS_XLOCALE_SUPPORT...
