Subject: [PATCH] fix removal of {cpu,machine} links on mingw/msys
|
|
|
a85e8e |
|
|
|
a85e8e |
At least on Windows 2003 using "ln -s dir1 dir2" in msys shell succeeds,
|
|
|
a85e8e |
but results in what looks like hard link. Subsequent "rm -f dir2" (e.g.
|
|
|
a85e8e |
during second config.status invocation) fails. Check that we also can
|
|
|
a85e8e |
remove link to directory.
|
|
|
a85e8e |
|
|
|
a85e8e |
Make it more clear in message that we are checking "ln -s".
