[fpc-devel] minor issue building fpc

[Martin]

Not sure if that is a known issue. Or considered an issue at all.

But 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)
