ok, so it works for paths - but what about other arguments, that are
not paths, just simple strings? They are also changed.
String "search \\me" is not the same as "search //me".
Example: given two "grep"-like programs, one compiled with cygwin, one
compiled without cygwin, I have to CreateProcess() with different
argument (different search string) to achieve same results - otherwise
one will search a file for "search \me" and the other for "search
\\me".
I don't know which program (cygwin/windows) is going to be executed.
Do I have to check before execution if the program is compiled under
cygwin and implement different logic in that case? From what I
understood so far this is the only way?
