The real problem is using the same variable name for the path of the
gzip executable and the default options.  gzip could gain support for a
new variable, something like GZIPFLAGS or GZIPOPT, that would take
priority over GZIP when specified.  Then Kalev could avoid the problem
by setting GZIPOPT=-9 .
