This looks like an error message from the cmd shell. "./" is sh shell
syntax; it assumes "." is not in PATH.

What does M-: shell-file-name show? If it's something that ends in
"cmdproxy.exe", then you are running the cmd shell.

What version of ada-mode? (M-x ada-mode-version)

What keystrokes are you using to invoke this?

If it's ada-mode 5.x, C-c M-r, then you can change
the variable ada-build-run-cmd in your .emacs:

(setq ada-build-run-cmd "${main}")

Then restart emacs and try again.

You can also use this variable to specify command line args,
but Makefiles are better in the long run.

You can also override ada-build-run-cmd with run_cmd in an ada-mode
project file; see the Emacs help for this variable (it should be in the
info manual, but it's not).

I always run Emacs on Windows with either Cygwin bash or MSYS2 bash as
the shell.
