Anyway, it is a feature only used by Project Builder. Project Builder 
uses it
to keep a list of validated precomps. If a precomp is listed in 
trust-file then
compiler skips validation tests and use it directly. If precomps are not 
used
in your project then Project Builder should not supply this argument, 
because
it is useless.

User is not suppose to use this compiler option directly. Project 
Builder adds
this  option with appropriate parameters. If it is supplying two 
arguments
(instead of one) then it can be a bug in Project Builder. Please file
appropriate bug report, if that is the case.

-cpp-precomp :
Use Apple's own preprocessor, which supports precompiled headers.
(It is used by default for C and Objective C)

-no-cpp-precomp :
Do not use Apple's own preprocessor. Use standard GNU preprocessor.

More documentation is available at
- /DeveloperTools/Preprocessor/PreprocessorTOC.html from Apple ADC 
website.
- on your disk (if you have installed Developer Tools) at
  /Developer/Documentation/DeveloperTools/Preprocessor
Documentation mentions -traditional-cpp, which is identical to 
-no-cpp-precomp.
Use of -no-cpp-precomp is recommended. We plan to change meaning of
 -traditional-cpp, because it carries different meaning in outside GNU 
world.
