Classification:UI/Usability Reproducible:Always
 
Summary:
When clang fails to find a file during compilation, Xcode reports a generic error even though clang output a specific one.

Steps to Reproduce:
* Build a project with clang as the compiler and a missing source file. (Example attached.)

Expected Results:
The error messages produced by clang:
“clang: error: no such file or directory: '/Users/jayton/Projects/missing_file/missing.c'”
“clang: error: no input files”

Actual Results:
“Command /Developer/usr/bin/clang failed with exit code 1”

Regression:
None known.

Notes:
The unhelpful error is produced by gcc too, but there doesn’t seem to be any helpful output to use in that case.
