#731 directories lost after restarting - in multi directories

[Amir Mohammadi]

After restarting devc++ i see this message

The following problems were found during validation of compiler set "TDM-GCC 4.7.1-2":
The following binary directories don't exist:
"C:\Program Files\CodeBlocks\MinGW\bin"
"C:\Program Files\CodeBlocks\MinGW\mingw32\bin"
The following C include directories don't exist:
C:\Program Files\CodeBlocks\MinGW\include"
"C:\Program Files\CodeBlocks\MinGW\lib\gcc\mingw32\4.7.1\include
The following C++ include directories don't exist:
C:\Program Files\CodeBlocks\MinGW\include"
"C:\Program Files\CodeBlocks\MinGW\lib\gcc\mingw32\4.7.1\include"
"C:\Program Files\CodeBlocks\MinGW\lib\gcc\mingw32\4.7.1\include\c++
Would you like Dev-C++ to remove them for you and add the default paths to the valid paths?
Leaving those directories will lead to problems during compilation.
Unless you know exactly what you're doing, it is recommended that you click Yes.

This error occur when i set include, bin, or lib directories to multi directory.
if i set only one directory to them no error occur.

for example :
if i set bin directory to
"C:\Program Files\CodeBlocks\MinGW\bin"
"C:\Program Files\CodeBlocks\MinGW\mingw32\bin"

that error occur
but if i set bin directory to only
"C:\Program Files\CodeBlocks\MinGW\bin"
every thing is ok!
