I don't believe in this solution:

- The above error messages are not Cygwin gawk error messages.  They
  look like bash error messages.  Bash doesn't understand CRLF line
  endings in scripts unless you explicitly allow that.

- /cygdrive/c/Program Files/Git/bin/awk is apparently the name of a
  shell script.  /cygdrive/c/Program Files/Git/bin/awk is certainly
  not /bin/awk.

- /bin/awk is a symlink to /bin/gawk.exe, an executable.  If you call
  dos2unix on an executable, the executable will be either unchanged,
  or broken with a high probability.

- Even if it doesn't matter in this scenario, Cygwin's gawk understands
  CRLF line endings in awk scripts.
