The file script/gzparam.c is only related to GZIP by the fact that the text line printed on stdout will be inserted into the linux.kgz file as a GZIP comment, it has nothing to do with the GZIP format itself. If you make and execute this gzparam manually, you will see a line (depending on .config) printed on stdout like: min_gujin_version=0x102 maskcpu=0x800000F0 maskDflags=0x021 \ loadadr=0x100000 maskvesa=0x... gzparam means: kernel parameters to be inserted in the comment line of the GZIP kernel file - to get a linux.kgz
The file script/gzcopy.c would be better distributed in a GZIP package if there was one such package and everybody upgrades this package before trying to compile the kernel. But that file can also be considered as a better way than using a script with sed/awk/cut/cat - its basic use is a single string manipulation (initialise and concatenate text strings - and insert it in a file at a defined offset). This utility is not made to evolve at all, and is so simple it does not worth bothering - a bit like: Linux/arch/i386/boot/tools/build.c . Note that I also send a message to jloup at the GZIP homepage, but I am not sure I want to add another dependency on GZIP package to build the kernel.
Etienne.
