grep restricts its use of grep to things that are effectively fixed strings, in order to remove a recursive dependency on a "good" grep that supports arbitrarily long lines. However, mmap-anon.m4 has one such instance. This patch, suggested by Rainer Orth, removes "special" characters from the string being sought. 

Ok?
