So the question is, why has GNU Emacs another another PATH value  
active? Do launch it from some menu? I looks as if your login shell  
provides a different environment than what you use in an interactive  
shell. If you fix this issue, then GNU Emacs will find the same  
compiler as you in some shell.

As I showed in my examples: you can use env to set particular  
environment variables.

Then my guess is that some environment variables reset the value. You  
can, for example do M-x compile RET and then erase the default make  
command and substitute it with env or printenv to see which  
environment the compile process sees. Then some corrections can be made.

I don't see this. There is a customisation group for the compilation  
process (C-h f compile RET and you'll find a hint in the *Help*  
buffer or via menus Options -> Customize Emacs -> Specific Group…,  
name completion works), but there is nothing to set the compiler  
explicitly. This is done in the shell or in Makefiles, as determined  
by a configure script for example, or set by the programmer.
