Summary: [4.8 regression] g++ preprocessor output includes
comments meant for GNU C Library files
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor

Example input and output files
I've found that g++ 4.8.x preprocessor output unexpectedly includes comments
meant for GNU C Library files.
To illustrate this problem, I ran the g++ preprocessor on test.hpp using as
follows
g++ -C -E -o test-<gcc-version>.hpp -P test.hpp
With g++ 4.7.3, this generated the expected output file. However, with g++
4.8.0, 4.8.1, and 4.8.2 the generated output file unexpectedly contained a
number of comments meant for GNU C Library files.
