--- Comment #2 from gcc-user at riseup dot net --- > Note swapping out parts of the build system isn't tested/supported. This is both a gcc and GNU libtool bug, gcc is passing invalid flags and libtool is silently hiding the fact. I understand that slibtool may be untested in gcc, but since its actually doing the right thing here and has several benefits over GNU libtool (Maintained and readable codebase) it would be very appreciated if this can be fixed. > Can you quote where the "invalid" -lvtv is present? Honestly the gcc build system is confusing for me, but see this comment from the gentoo issue. https://bugs.gentoo.org/767706#c7 Briefly it explained that -lvtv comes from -fvtable-verify=std in a gcc spec file and is propogated to Makefile.in by gcc/Makefile.def.
