Not sure if that is a known issue. Or considered an on windows, if you specify the INSTALL_PREFIX with a trailing "\" (which afaik is a normal way to specify a directory), install will fail. make.exe install INSTALL_PREFIX=c:\FPC\tag_2_6_0\ FPC=C:\fpc\SVN\tag_2_6_0\compiler\ppcx64.exe

The problem is, that in the resulting command-line "--prefix=c:\FPC\tag_2_6_0\ " the "\" escapes the following space. All other path separators are given as "/" (forward slash)

I'm not aware of any standard for specifying directory names on command lines that suggests either including or not including a trailing directory separator.

The reason that \ escapes the next character is because of make's Unix heritage. The above --prefix parameter is just a symptom, the actual escaping problem already occurs when make interprets the command line you specified.

In summary: never add a terminating backslash to make parameters.

Standard directory operations expect *no* trailing directory separator. In other places, where both file or directory names are accepted, a trailing delimiter could help to distinguish between both, but is not normally required.
