I don't think that its buggy behavior,
windows make, be it cygwin, mingw32 (and   probably also msys)
do expect only forward slashes for directory separators
and always handles backward slashes as escapes.

  Using forward slashes for all parameters of a make call should 
avoid the problem...
  If you really wanted backward slashes, then, simply use escaped backslashes,
i.e. two in a row,
make install PREFIX=c:\\lazarus\\fpc\\2.7.1\\
