--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Tamar Christina from comment #0) > According to https://gcc.gnu.org/install/build.html this is a supported > build style Nope. See https://gcc.gnu.org/install/configure.html "First, we **highly** recommend that GCC be built into a separate directory from the sources which does **not** reside within the source tree. This is how we generally build GCC; building where objdir is a subdirectory of srcdir should work as well; building where objdir == srcdir is unsupported." and https://gcc.gnu.org/wiki/InstallingGCC and https://gcc.gnu.org/wiki/FAQ#configure We've been trying to get people to stop running ./configure for as long as I can remember, so I don't see the point in a patch to help them keep doing it.
