Add --with-static-standard-libraries to the top level
gdb should normally not be linked with -static-libstdc++. Currently this has not caused problems, but it's incompatible with catching an exception thrown from a shared library -- and a subsequent patch changes gdb to do just this. This patch adds a new --with-static-standard-libraries flag to the top-level configure. It defaults to "auto", which means enabled if gcc is being built, and disabled otherwise. ChangeLog 2019-08-19 Tom Tromey <tom@tromey.com> * configure: Rebuild. * configure.ac: Add --with-static-standard-libraries.
