fix #1141 by fixing #1120 differently.

Browse Source 
I still don't see why r8592 has an effect, except calling OSRImportFromProj4()
in locale "C".  Just setting LC_NUMERIC probably resolves the side effects
leading to #1141 without reopening #1120.

But there might be - even more subtle - side effects left - watch out.
