New application creation failure in NIOS II - Quartus20.1

Note in 19.4 when opening an 'Nios II Command Shell (Quartus Prime Pro 19.4)' command shell and running 'nios2-bsp-create-settings' results in "nios2-bsp-create-settings: command not found".
However running 'nios2-bsp-create-settings.exe' (with .exe extension) does work.
In the Makefile there is some logic for this:

UNAME = $(shell uname -r)
ifeq ($(findstring Microsoft,$(UNAME)),Microsoft)
WINDOWS_EXE = .exe
endif

Refer to https://community.intel.com/t5/Nios-II-Embedded-Design-Suite/Error-s0-Error-during-execution-of-quot-C-intelfpga-20-1-quartus/td-p/1191914 as the uname is case dependent and only works for WSL1.

Probably your 'nios2-bsp-create-settings' is executed without '.exe' extension you can try to adapt the Makefile to use a hardcoded ".exe" extension
