From 115c0381c235100d7b05d9751767017a9ee325c4 Mon Sep 17 00:00:00 2001 From: Nathan Phillip Brink Date: Tue, 18 Oct 2011 03:42:17 +0000 Subject: Use AM_PATH_GPGME macro from gpgme instead of home-built gpgme detection. Fixes compilation on Gentoo, where CPPFLAGS=-I/usr/include/gpgme is necessary. The AC_SYS_LARGEFILE macro call has to be before the GPGME checks, otherwise the GPGME header gives an error about ABI incompatibilities.
