Comment 6 for bug 699081

I think the problem are the fprintf calls in src/file.c
Just setting the locale to C will proobably not work well
with future
localization of pcb messages. Setting the locale to C,
writing the file
and setting it back to the original one is not thread-safe
(I don't know
if pcb uses threads though).
One solution would be to use the locale-independent
g_ascii_strtod()
from glib.
