+
+ * am/libpdftex.am (libpdftex_a_CFLAGS): Enable compiler warnings.
+
+ Avoid most compiler warnings:
+
+ * ptexlib.h, writejbig2.h: ANSI C function prototypes.
+ * avlstuff.c, mapfile.c, utils.c, vfpacket.c, writeenc.c,
+ writefont.c, writeimg.c, writejbig2.c, writet1.c, writettf.c:
+ ANSI C function definitions.
+
+ * avlstuff.c, mapfile.c, utils.c, writeenc.c, writefont.c,
+ writejbig2.c, writepng.c, writet1.c, writettf.c: Declare
+ functions as static.
+
+ * ptexlib.h: Add prototype for imagecolor().
+ * inc-epdf.h: New file with prototypes for is_subsetable(),
+ epdf_check_mem(), epdf_create_fontdescriptor(),
+ epdf_mark_glyphs(), get_fd_objnum(), get_fn_objnum(), and
+ embed_whole_font() ...
+ * epdf.[ch]: ... removed from here.
+ * epdf.[ch]: #include "inc-epdf.h".
+ * inc-extra.h: New file with prototypes for stripzeros() and
+ epdf_write_enc() ...
+ * epdf.h: ... removed from here.
+ * epdf.c, utils.c, writeenc.c: #include "inc-extra.h".
+ * am/libpdftex.am (libpdftex_a_SOURCES): Add the new files.
+
+ * writejbig2.c: Avoid use of possibly uninitialized variables.
+
+ * utils.c, writefont.c, writet1.c, writettf.c:
+ Declare various function params and args, local vars, and struct
+ members as const.
+
+ * writet1.c (append_cs_return): Drop unused local variable 'k'.
+
+ * avlstuff.c (destroy_oentry, PdfObjTree_free),
+ writet1.c (free_glyph_names):
+ Skip unused static functions (via #if 0 ... #endif).
+
+ * utils.c (newcolorstack): Don't use value of xretalloc(),
+ xretalloc(addr, n, t) already assigns the new pointer to addr.
+
+ * avl.c (avl_delete): Don't reuse const input param for
+ non-const return value.

* am/libpdftex.am: Add dependency on $(XPDF_DEPEND).
