[FFmpeg-devel] [PATCH] configure's to_lower and to_upper fix on *bsd

[Pierre d'Herbemont]

Hi,

here, on Mac OS X, (should be a BSD issue):
$ echo "hello z" | tr '[a-z]' '[A-Z]'
HELLO ]

This cause configure to generate a bad crafted config.h. Here is a fix  
for that, as suggested by the BSD tr's man page.

Pierre.
