In the debdiff:
+if [ -n "${DEB_HOST_GNU_TYPE:-}" ]; then
+ CC="$DEB_HOST_GNU_TYPE-g++"
+ PKGCONFIG="$DEB_HOST_GNU_TYPE-pkg-config"
+else
+ CC=gcc
+ PKGCONFIG=pkg-config
+fi
Thanks for proposing this, but how come g++ becomes the compiler
instead of gcc when cross-compiling?
While simply replacing "-g++" with "-gcc" in the patch could fix it,
I'd rather adapt another patch proposed for libthai in bug #983522
which ensures the compiler does not get changed by accident:

Thanks again for the sync.
