+[PATCH] squashfs-tools: unbreak builds without gzip support
+
+The initialization of gzip_comp_ops if gzip support is disabled is
+missing 2 null pointers, causing the id element to be initialized to 0
+rather than ZLIB_COMPRESSION, which breaks all the compressor functions
+as they loop until finding the correct element or id = 0.
