Sorry I can't comment yet.

But I must point out that the original ln command is incorrect, which creates an incorrect relative link usr/bin/gcc-4.8 under /usr/bin/

Correct command is

sudo ln -s /usr/bin/gcc-4.8 /usr/bin/gcc

or

sudo ln -s gcc-4.8 /usr/bin/gcc

Your line

Copygcc‬‬ ‫‪-g‬‬ ‫‪-m32‬‬ ‫‪-o‬‬ ‫‪skip‬‬ ‫‪skip.c

is ASCII broken. There are strange (invisible) characters before the spaces. Check it here.

Also, to run gcc with -m32 flag on, you need to install gcc-multilib first:

Copyapt-get install gcc-multilib

You are not configuring the correct config file. Check this out:

https://wiki.archlinux.org/index.php/Zsh#Configuring_.24PATH

Check that gcc is installed correctly:

brew install gcc
brew link gcc48

Create an alias to whatever link brew created and put it in your .zshrc

cd /usr/local/bin
ls cpp*
ls c++*

alias gcc=/usr/local/bin/<whatever_link_you_found>

Maybe simple...

sudo apt-get install gcc

... could be enough?

Set the environment variable path as C:\msys64\ucrt64\bin in case if you have installed gcc using pacman -S mingw-w64-ucrt-x86_64-gcc.

OR

You can install gcc using: pacman -S mingw-w64-x86_64-gcc and set environment variable path as C:\msys64\mingw64\bin.

You need to update your system:

sudo apt update
sudo apt upgrade
sudo apt install gcc

try download binaries of gcc.exe and put it in a folder and add it in your PATH. Then you should be able to run gcc.exe in your WSL.

for me, was using MinGw and put all the binary for my sub system in /bin directory (added it to path, work perfectly)

You can install gcc by running setup-x86.exe or setup-x86_64.exe again. The gcc package is in the Devel category:
