RE: basename function in 4.3 cygwin

[Ronald Hoogenboom]

I checked the native windows port of gnu-make I have (x86_64-pc-msys, version 
4.2.1) and it exhibits the same behavior as what I see on cygwin. Apparently 
this is not cygwin specific.

Since you state that there were some changes done between 3.81 and 4.x with 
regards to the backslash path separator, I guess that is what caused this 
regression.

FWIW, I'd actually expect it to be the other way around: to hear that Make 3.81 
considered a backslash to be a directory separator, whereas Make 4.3 did not.  
That's because some years ago the Cygwin developers decided they want no longer 
support native MS-Windows file names, only
Posix- style file names.

But other than that, I agree with Paul: this should probably be taken up with 
the Cygwin developers through their mailing list.
