# Usage: bash misc_env

# Zaikun 20260215: As of 20260215, the following is not needed. In addition, on windows-2025, it will
# make gfortran fail due to missing DLL, and consequently, Makefile fail with Error -1073741515
# (interestingly, the same problem does not occur on windows-11-arm); more seriously, it even makes
# windows-2025 fail to recognize cmd.exe ("The term 'cmd.exe' is not recognized as a name of a cmdlet,
# function, script file, or executable program"). In brief, it will destroy the windows-2025 runner.
# No idea why. Anyway, don't do it!
