Ping. http://gcc.gnu.org/ml/gcc-patches/2012-09/msg00459.html
Full text of previous message and context at URL above. No comments or code changes since. Patch description left below for convenience. > > Add flags to disable system header canonicalizations. > > Libcpp may canonicalize system header paths with lrealpath() for diagnostics, > dependency output, and similar. If gcc is held in a symlink farm the > canonicalized paths may be meaningless to users, and will also conflict with > build frameworks that (for example) disallow absolute paths to header files. > > This change adds -f[no-]canonical-system-headers to the gcc command line, and > a configure option --[en/dis]able-canonical-system-headers to set default > behaviour, allowing the user to select whether or not to implement r186991. > Default is enabled. See also PR c++/52974. > > Tested for regressions with bootstrap builds of C and C++, both with and > without configure --disable-canonical-system-headers. -- Google UK Limited | Registered Office: Belgrave House, 76 Buckingham Palace Road, London SW1W 9TQ | Registered in England Number: 3977902
