Werner Lemberg	c9bbc2419a	Add internal functions `FT_Trace_Disable' and `FT_Trace_Enable'.

Alexei Podtelezhnikov	3d4ab6bac1	[pcf] Massive unsigning (part 1). Unofficial specifications hesitate to use unsigned 32-bit integers.

Alexei Podtelezhnikov	f24dbb2811	[pcf] Use unsigned types. * src/pcf/pcf.h (PCF_Encoding): Use unsigned `enc'. * src/pcf/pcfdrivr.c (pcf_cmap_char_{index,next}): Ditto. * src/pcf/pcfread.c (pcf_get_encodings): Use unsigned types.	7 years ago
