My old cc1.c code support the -pipe option to gcc.  This results in ccp 
feeding directly to cc1 over the network (without a temporary file) and the 
output of cc1 feeding directly to 'as'.  GNUcc spits out the assembler code 
for each function as it finishes it, so cpp, cc1, and 'as' all run in parallel 
during a single compile - and no temporaries are needed.  By running cc1 and 
'a' separately, distcc can do this too!
