Another set of very simple tweaks to a range of source files to remove

warnings. Nothing contentious in here I hope!

base/gdevpdf.c: Make the fact we're ignoring the return value of fread
explicit by casting to void.

base/gdevsj48.c: Remove unused var.

base/gdevtknk.c: Avoid gcc warning by not needlessly assigning within
expression.

base/gdevimgn.c: Fix type declaration, make function static.

base/gxdcolor.c: Remove unused var.

base/gdevwts.c: Comment out unused function, cast unused return value from
fread to void, remove unused vars.

base/gdevo182.c: Be more explicit in type definition to stop warning.

base/gdevlp8k.c: Remove unused var.

base/gdevpdfu.c: Cast unused return value from fread to void.

base/gdevlbp8.c: Cast unused return value from fread to void.

base/gdevokii.c: Explicit cast to int to shut up stupid compiler.

base/gdevpdtd.c: Add const to arg to avoid warning.

base/gserror.h: Do some macro magic to ensure that the macro always evaluates
it's arg strictly once, insists on being followed by a semicolon, and behaves
well with surrounding if/else structures etc.

base/gxp1fill.c: Remove unused var.
