@@ -46,7 +46,6 @@ A (slightly) ordered set of tasks for crosstool-NG. Written in a cryptic languag
   [ ] add passthrough to configure, for host/target
 [ ] Read/spellcheck configs & scripts
 [ ] 'ct-ng olddefconfig'
-[ ] Install config.gen so that it is not rebuilt in the installed configurations
 [ ] Install a "trap" C++ compiler as ${CT_TARGET}-g++ during pass-1/pass-2 to trap attempts to compile target code with g++ (currently glibc detects host g++ and warns that it uses g++ w/o target triplet)
   [ ] Somehow it needs to be functional during the configure step - export env var while running in CT_DoExecLog with CFG level, and forward it to host compiler?
 [ ] elf2flt not compatible with multiple linkers enabled in binutils (ld.bfd + ld.gold) - fix upstream?
