Fix incorrect usage for file-access.

[oontvoo]

Immediate symptom is that in src/stream.c, declarations for ftello(...) and fseeko(...) are not available.

(Errors will be raised if compiled with -Wimplicit-function-declaration

You hit the delete or backspace key a little too much resulting in
the following brokenness...

-# include <stdlib.h>

No. I just added my comments here to notify you of the issues in your patch, that's all.

Further research suggests it's only API levels 21, 22, and 23 which were broken. Prior to that the defines were just ignored by the NDK.

Actually, this also depends on the ndk version.
