Revisiting this...
I just checked in the recipe for building Emacs 28.0.90 on MinGW-w64
(MSYS2) with native compilation enabled and found a serious problem.
The Emacs MinGW-w64/MSYS2 package now depends on libgccjit package,
which means that libgccjit will be present when Emacs is installed. But
if Emacs runs without its bin/ directory in PATH, libgccjit is not
functional (an error about missing as.exe is shown.)
Creating a desktop icon for runemacs.exe and starting Emacs from there
is common. Also for MSYS2 users is common to work with multiple
architectures (mingw, clang, ucrt with their 32/64 bits variants)
simultaneously, and putting the binaries of one of those architectures
in global PATH is problematic.
Hence it would be very convenient to use libgccjit without touching PATH.
I ask again: would it be ok to add emacs.exe directory to PATH from
runemacs.exe or emacs.exe itself?
Set PATH for the emacs instances used for generating the .eln files?
Other solution?
