Issue #1848 resolved
The 5D3 build seems to be broken since this patch:
It's causing this error:
[ VERSION ] ../../platform/5D3.113/version.bin [ VERSION ] ../../platform/5D3.113/version.c [ CC ] version.o [ CC ] zebra.o In file included from ../../src/zebra.c:386:0: ../../src/cropmarks.c: In function 'cropmark_draw': ../../src/cropmarks.c:326:33: error: 'transparent_overlay_hidden' undeclared (first use in this function) ../../src/cropmarks.c:326:33: note: each undeclared identifier is reported only once for each function it appears in make: *** [zebra.o] Error 1
It looks like some of the other builds may also be broken.
