/bin/sh: !: not found

Hi.

I using version from CVS, and after update tried to run `make
distclean'. For some reason my GNUMakefile was deleted, so Makefile is
used by gmake and I got an error message (see Subj)

The reason is 
	@if ! [ -f GNUmakefile ] ; then \
           ^^^ in the Makefile

To fix it should be changed to
	@if [ ! -f GNUmakefile ] ; then \

This problem exists in Makefile and src/Makefile, maybe somethere else
