Subject: Add explicit check for EGREP in configure.ac
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=31cde7247638a50c2302744984732064505b7d85;p=lyx.git

Add explicit check for EGREP in configure.ac

It is used in lib/Makefile.am and we were relying some autoconf macros
to define it as a side-effect. This is not the case anymore as of
autoconf 2.72.
