All,

    I've been playing with the distcc/armcc combo for a while now and though 
I'd like to go through the formal development process, it's not all that 
straightforward and I don't have that much free time (enough ranting).

    To the point, armcc/armcpp won't compile anything that it's not expecting 
(*.i, *.ii, etc. vs. *.c, *.cpp, etc). Apparently it doesn't even try to open 
it, it just dies with a semi-cryptic C3065E: type of <file> unknown. I wrote a 
DISTCC_KEEP_FILETYPE flag so that armcc is happy and it appears to working 
correctly (I haven't gotten a full compile yet due to lack of time and a 
complex makefile system).

    Also, I had to setup TMPDIR=c:/cygwin/tmp/ or armcc kept erroring with a 
can't find /tmp/file.c. If I gave it a relative path it was fine but it didn't 
like an absolute path. A co-worker and I stumbled upon giving it the DOS path 
instead of /cygdrive/c/cygwin/tmp/ that CygWin thinks it is and that was the 
last piece of the puzzle.

    Hope this helps everybody running a distcc/armcc/cygwin chain.
