[giflib-devel] [Patch] strtok() -> strtok_r()

[Ed S. <ed...@nu...>]

Hi there,

While trying to build giflib on CloudABI (https://nuxi.nl/), I noticed
that giflib uses the strtok() function in a couple of places. The use
of strtok() is heavily discouraged, as it is not thread-safe. This
potentially makes it harder to use giflib in multi-threaded programs.

Attached is a patch to let giflib use strtok_r() instead. It also
removes some of the casts in there, which look suspicious. The
functions are already called with arguments of the right type.

Best regards,
