How do I uninstall the installation that I created with the building of gcc6? I did a search on duckduckgo for,

cygwin how to uninstall gcc after building it

and found nothing that could help me.  Right now I have two installs of gcc: v7.4.and v6.4.0.

e608313 AT HOR711318E ~/gcc/gcc-6.4.0
$ which gcc​
/usr/local/bin/gcc​
​
e608313 AT HOR711318E ~/gcc/gcc-6.4.0​
$ /usr/bin/gcc --version​
gcc (GCC) 7.4.0​

​
How can I have just v7.4.0?  I tried searching around and nothing.  Any help would be greatly appreciated.  I know I can delete the folder and start all over, but I prefer to keep this one as it was.  Or do you think that I should start from scratch?  Thanks.

josé

Thanks, Ken.  Maybe I should go back to my original plan to build with gcc-7.4.0.  These are all the errors that I am getting with gcc 6.4.0, which I just took two days to build:
