Neither of these should be needed, because ZLIB_CONST should be defined.
configure:6254:
enabled zlib && add_cppflags -DZLIB_CONST
This works correctly for me:
$ make V=1 libavcodec/tscc.o
gcc -I. -Isrc/ -D_ISOC99_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
-D_POSIX_C_SOURCE=200112 -D_XOPEN_SOURCE=600 -DZLIB_CONST -DHAVE_AV_CONFIG_H
-std=c99 -fomit-frame-pointer -pthread -D_GNU_SOURCE=1 -D_REENTRANT

$
Perhaps instead investigate why it isn't working for you?
