[cfe-commits] [patch] Avoid gcc warning when using the clang preprocessor

[Rafael Espindola]

I am trying to use clang to preprocess source code and pipe the output
to gcc. With a current clang and gcc 4.5 I am getting the warning

line-map.c: file "test.c" left but not entered

This is caused by clang exiting the main file "test.c":

# 1 "test.c" 2

The attached patch fixes the problem.

Cheers,
