Subject: [PATCH] 'yes' within the path sets wrong config variables
It seems that the 'AC_EGREP_CPP(yes...' example is quite popular
but being such a short word to grep it is likely to produce
false-positive matches with the path it is configured into.
The change is to use a more elaborated string to grep for.
