Post-build fails in windows with wsdl2aws_templates-p_f3be9e58aeef1fc8860f3b9e1f1958650e8eab7a.ads: No such file or directory

I'm using Windows 10, but others have reported similar here and here on Windows 11. When trying to build AWS in Alire version 2.0.1 (specifically YASS), it fails at the very last stage with messages similar to:

It appears to happen when it hits aws/tools/wsdl2aws-templates/Makefile.

When I check C:\Users\Dell\AppData\Local\alire\cache\builds\aws_24.0.0_2b75fe6d\76ffc400ad3402a54fb70c8123b2c7e3ca05994d4ebde43aa84bc3b5eaa2e888\.build\x86_64-w64-mingw32\common\src I get:

Except it seems to be looking for ../../.build/x86_64-w64-mingw32/common/src\wsdl2aws_templates-p_f3be9e58aeef1fc8860f3b9e1f1958650e8eab7a.ads
(note the \ after /src and -p_f3be9e58aeef1fc8860f3b9e1f1958650e8eab7a)

If you want to download a copy of yass on windows with alire and just run alr update && alr build you can see what I mean. It's weird because sometimes aws builds but other times it doesn't; it may be because yass is using the template engine, so you may be able to replicate this with another app using it.

Compiles fine on MacOS and Linux.

EDIT: Just wanted to note, that this does not happen with version 23, just 24.

Reproduce the failure on Windows with YASS using alr update && alr build, then inspect tools/wsdl2aws-templates/Makefile and its gen-templates step. Compare the AWS 24 and 23 behavior, focusing on the generated path and the missing wsdl2aws_templates-p_*.ads file; done means the Windows build completes successfully.
