Subject: Support for "sunpro make"

The attached diff file for cccp.c adds support for the sun make's 
automatic dependency checking.  This version of `make' is known
as "sunpro make" under SunOS 3.5 & is the default `make' under SunOS 4.0. 

Sun's automatic dependency checking works by having the pre-processor
log on a seperate file all include files as it processes the file.
The log file (and the current target name) are gotten from the
environment variable "SUNPRO_DEPENDENCIES", which is set by
"sunpro make".

As I don't have access to the source & none of this is documented, 
this patch may not be exactly right. I figured this stuff out
by looking at a "make -dd" logfile & guessing.  However, it 
seems to work here.
