Re: GCC of MinGW was updated to 4.5.0

[Tatsuro MATSUOKA]

Hello

I have found a problem that gcc-4.5.0 may not work correct when it is not 
installed in C:\MinGW.
This is not good at octave packaging like current octave-3.2.3/mingw.

But this bug(?) can be avoided by addinf -I/mingw/include
 
Please see the threads,
http://old.nabble.com/gcc-4.5.0-:-Is-flag--I-mingw-include-always-needed---td27901832.html

I moved my mingw directory to c:\MinGW and try to test build octave by new gcc.

Regards

Tatsuro
