gcc-10 branch builds out version 12 ALL THE TIME ?

[Pei Jia <jiapei@xxxxxxxxxxxxxxxx>]

Hello:

I'm facing this issue addressed at 
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100101 
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100101> and 
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100102 
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100102> . My environment 
is Ubuntu 20.04. The current gcc version is of 10.3.0, from the default 
repo. I was trying to rebuild gcc by checking out the branch gcc-10:

   /➜  gcc git:(gcc-10) ✗ git remote -v/
   /origin    git://gcc.gnu.org/git/gcc.git (fetch)/
   /origin    git://gcc.gnu.org/git/gcc.git (push)/
   /➜  gcc git:(gcc-10) ✗ echo "$(git branch -vv)"/
   /* gcc-10 461f937b472 Daily bump./
   /  master 461f937b472 [origin/master] Daily bump./


However, even if it's successfully built, it built out  a version of 12, 
which is NOT what I expect.

   /➜  gcc git:(gcc-10) ✗ gcc --version//
   //gcc (GCC) 12.0.0 20210627 (experimental)//
   //Copyright (C) 2021 Free Software Foundation, Inc.//
   //This is free software; see the source for copying conditions. 
   There is NO//
   //warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR
   PURPOSE./

My configuration to build *gcc-10* is as:

   /➜  gcc git:(gcc-10) ✗ $PWD/../gcc/configure --prefix=/usr/local
   --enable-languages=c,c++,fortran,go --enable-multilib /

Can anybody give me a hand please?


Thank you very much


Best Regards
