rizin rz-gg: Cannot find 'gcc' on windows 11

Work environment

Questions	Answers
OS/arch/bits (mandatory)	Windows 11 25H2 Build 26200.6899 x64
File format of the file you reverse (mandatory)	(not exactly reversing, but tried compiling a c file)
Architecture/bits of the file (mandatory)	(tried compiling to x86)
`rizin -v` full output, not truncated (mandatory)	`rizin 0.8.1 @ windows-x86-64 commit: c009cb739ca4fd289e634c2bea432d1e7bcd3676`

Expected behavior

The shellcode should be compiled and given as output.

Actual behavior

'gcc' -fPIC -fPIE -pie -fpic -m32 -fno-stack-protector -nostdinc -include 'C:\Users\abinr\Desktop\Tools\rizin-win-installer-clang_cl-64\include\librz/sflib'/'windows-x86-32'/sflib.h -z execstack -fomit-frame-pointer -finline-functions -fno-zero-initialized-in-bss -o 'shellcode.c.tmp' -S 'shellcode.c'

''gcc'' is not recognized as an internal or external command,
operable program or batch file.
ERROR: egg: failure while parsing 'shellcode.c'
ERROR: rz-gg: cannot load file "shellcode.c"

Steps to reproduce the behavior

Tried to follow the official guide from here.
shellcode.c contents

int main() {
    write(1, "Hello World\n", 13);
    return 0;
}

Command used to compile: rz-gg -a x86 -b32 shellcode.c
The following command gives the same error: rz-gg -z -o out.h -kw32 shellcode.c

Output of gcc -v:

Same issue for rz-gg -a x64 -b64 shellcode.c

The issue is in the latest commit too:

rizin 0.9.0 @ windows-x86-64
commit: ef21a25cc995e2e0e2276f46fd64586554bae254

I tried changing the mingw thread model to win32 and it still exists: output for 'gcc -v'
