People have said this but I don't see it:
$ which cpp
/usr/bin/cpp
$ ll /usr/bin/cpp
lrwxrwxrwx 1 root root 7 2005-08-21 15:01 /usr/bin/cpp -> cpp-4.0
$ ll /usr/bin/cpp-4.0
-rwxr-xr-x 1 root root 90232 2005-08-21 19:51 /usr/bin/cpp-4.0
$ ldd /usr/bin/cpp-4.0
linux-gate.so.1 => (0xffffe000)
libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7dee000)
/lib/ld-linux.so.2 (0xb7f2d000)
Using "strace -e open" doesn't show cpp opening at runtime any other
libraries.
What is xrdb/cpp *doing* in the 10% of the startup time? It doesn't
perform any I/O as gnome-settings-daemon does that instead, and streams
the contents of the files into xrdb's stdin.
