-For GCC trunk:

-  * [\[meta-bug\] bootstrap bugs for

-Additionally:

-Modify the [[building/cross-compiling]] shell script to configure GCC for
-building GCC with C++ support when building its second (i.e., final) version.
-
-Compiling a most-trivial C++ program used to work with GCC 4.2 and 4.3 (and the
-resulting binaries would also work), but linking fails with GCC SVN trunk:

-    collect2: ld returned 1 exit status
-
-Whether this defect report also applies to a natively-build GCC from SVN trunk
-has not yet been checked.
-
-[[Thomas_Schwinge|tschwinge]] suspects the problem to be a configuration issue
-of a GCC helper library, whose configuration setup has changed after GCC 4.3.
-
-The need for `-lpthread` is another story.  See the Debian glibc patches
-repository for details.
