C Backend not compiling.

I set the path to my pbcompilerc.exe but it does not work.

```
Compiling: audioengine.pb
  C:\Program Files\PureBasic\Compilers\pbcompilerc.exe c:\Users\agora\OneDrive\Bootleg\Purebasic\audioengine.pb --exe c:\Users\agora\OneDrive\Bootleg\Purebasic\audioengine.exe --run

--exe: Unknown switch

❌ Compilation failed (exit code 1)
