[cxx-conversion] gcc-4.7.0 on Cygwin and MinGW32 with --enable-build-with-cxx successes

Should --with-build-sysroot be default to --with-sysroot?

2012-05-25 Thread H.J. Lu
When --with-sysroot is used to configure gcc, build will usually fail if --with-build-sysroot isn't set. Should --with-build-sysroot be set to the same value as --with-sysroot by default if --with-sysroot is used? -- H.J.
