autosetup-find-tclsh generates without UNIX line endings.

When installing libjimtcl using Cygwin, I get the following error:

$ make install clean
libjimtcl is not currently installed.

The key error here is "/autosetup-find-tclsh: No such file or directory." This file is generated after the make command and can be found within the "./build/libjimtcl-1.0.0/autosetup/autosetup-find-tclsh" path. But I believe the issue is that the autosetup-find-tclsh file is not generated with Unix line endings.

If I run autosetup-find-tclsh directly, this is the error I get:

$ ./build/libjimtcl-1.0.0/autosetup/autosetup-find-tclsh
./build/libjimtcl-1.0.0/autosetup/autosetup-find-tclsh: line 7: syntax error near unexpected token `$'do\r''
./build/libjimtcl-1.0.0/autosetup/autosetup-find-tclsh: line 7: `for tclsh in ./'imsh0 $autosetup_tclsh jimsh tclsh tclsh8.5 tclsh8.6 tclsh8.7; do

If I change the line endings of autosetup-find-tclsh to UNIX, then I can run autosetup-find-tclsh, but then the entire make command cannot run because it always generates with Windows line endings.

Is there a way to get around this?
