File ghostscript-9.00-echogs.patch of Package ghostscript-library.887

Hi, while building ghostscript 8.62 with non-standard settings for
GLGENDIR, GLOBJDIR, ...
I noticed a few small inconsistencies in ghostscripts makefiles. The
attached patch should
fix these. I'm also building with a separate build directory.
Unfortunately, the resulting path
strings overflow a static buffer in echogs.c. The patch also changes
the size of these
buffers. I'm just including limits.h, I should probably guard this
with an HAVE_LIMITS_H
or something like this.

PS. I hope this message is appropriate for this list (or should gs-
code-review be
used for such things?)
