[distcc] [PATCH] Cygwin support (pid length fix)

[Aaron Lehmann]

Now you can steal the cycles of people running less enlightened
operating systems. distccd would work out of the box on cygwin, except
for the fact that PIDs on cygwin range up to the high millions. This
patch changes the maximum PID string length to 10 digits, enough to
fit the highest number that can be represented in a 32-bit pid_t.

Do any platforms have 64-bit pid_t's?
