[sane-devel] [PATCH] undef linux before defining STRINGIFY

[Niels Ole Salscheider]

Otherwise, "linux" will be expanded to "1" when it is stringified.

This is a problem for e. g. LIBDIR, which might contain a target triplet.
On my system, /usr/x86_64-pc-linux-gnu-gcc would expand to x86_64-pc-1-gnu-gcc.
