You can change global AllowDirectorySeparators 
(http://www.freepascal.org/docs-html/rtl/system/allowdirectoryseparators.html 
) to exclude '\' on non-Windows. I do this in my engine:

   {$ifndef MSWINDOWS}
   AllowDirectorySeparators -= ['\'];
   {$endif}

This way ExtractFilePath and friends behave correctly on non-Windows.

And I really, really wish this would be changed in FPC too... That is, 
AllowDirectorySeparators should be ['/'] on Unix, not ['/','\']. 
Backslash is a completely normal character in Unix filenames. The 
default value of AllowDirectorySeparators variable *should* be 
OS-dependent, just like PathDelim and others.
