dvipng 1.1 in teTeX 2.96.4

Hi again, 

that's hopefully the last report to dvipng, summing up my earlier mails
to teTeX-pretest.  below you find a patch for the following problems:


1)
OSF1 v4.0 and SunOS 5.5.1 don't have neither stdint.h nor inttypes.h.

I've added tests in configure for stdint.h and inttypes.h
and some fallback code if neither file is available.


2)
OSF1 v4.0 doesn't really have snprintf() (it's hidden in libdb.a), 
SunOS 5.5.1 doesn't have snprintf() at all.

snprintf is _only_ used in special.c for format strings "-r%dx%d" and "-g%dx%d".
those strings never can exceed STRSIZE (256), so I have changed those calls 
back to sprintf() for portability reasons.
