Well, whoever was mental enough to use '!' in variable names deserves
the breakage anyway! :-)
But hopefully, make-4.0 won't be such a pain make-3.82 was. What flew in
the GNU folks to release a highly backward-incompatible version as a
minor release? Seriously? Even if it fixed undocumented limitations, it
really broke more than a handfull of projects, of which high-profile
projects like the Linux kernel or the glibc. And I don't count the
others. Oh well... Sigh... :-(
