https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84637 --- Comment #2 from Martin Liška --- Thanks for explanation. Do you plan to remove it in the future from GCC or will you leave it there unmaintained?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84637 Jim Wilson changed: What|Removed |Added CC||wilson at gcc dot gnu.org --- Comment #1 from Jim Wilson --- The stabs support is obsolete and unmaintained. The best solution is to disable the stabs support for the compiler target you are trying to build. If you disable the stabs support for your target, the testsuite will stop running stabs tests, and you won't see these errors anymore. The stabs support can be disabled by removing the dbxelf.h reference in config.sub for x86 linux (and optionally other x86 targets), or by undeffing DBX_DEBUGGING_INFO somewhere in the config/i386 dir.
