--- Comment #2 from Matthew Niemerg <research at matthewniemerg dot com> --- I understand I am using clang as the compiler. I am trying to build gcc-4.9.2 with clang as my compiler. I have successfully used clang for compiling gcc-4.3.3, gcc-4.4.3, gcc-4.7.3, and gcc-4.8.4 from source but am now trying to compile with clang for gcc-4.9.2 and this fails as indicated in the original report, hence why I filed the bug report here. I will also submit this bug report to their bugzilla. Thank you.
