snapraid/configure.ac
Andrea Mazzoleni 31a8dc9a13 Comply wih the autoconf manual about SYSCONFDIR 
The manual says to allow to configure the dirs when calling
make, meaning that we cannot expand them in configure.ac.
Note that we use additional quoting to allow dirs with spaces
in the gcc command line.
This is done for the Window port of SnapRAID.
