Subject: [PATCH] Fix build failure with gcc-7

When function is declared inline but it is not static then compiler
assumes it could be potentially called from other translation
units. Hence it will inline the function within the translation unit and
at the same time it will generate object code for function with external
linkage. However both extern and inline variant *must* be the same and
therefore such function can not use any variables with static storage
duration. In our case functions in g3cat.c and pbm2g3.c are not called
from other translation units hence it is fine to mark then explicitly as
static and compiler won't generate other (problematic) extern variant.
