GTK3 new project "Script error"

[Sparkye]

Hello guys,
first of all, I must say that I am a complete newb in this.
I have downloaded the GTK+ bundle from http://www.gtk.org/download/win64.php extracted it to C:\gtk
Added User variable gdk-pixbuf with value C:\gtk\include\gdk-pixbuf-2.0
and variable gtk with value of C:\gtk
at the end of system variable Path I added ;C:\gtk\bin
In Code::Blocks I have added `pkg-config --cflags gtk+-3.0` to Settings->Compiler...->Compiler settings->Other options (which was blank before)
and also `pkg-config --libs gtk+-3.0` to to Settings->Compiler...->Linker settings->Other linker options

When I try to create new GTK+ project, I chose path and than I am asked to fill GTK's location, so I have inserted C:\gtk (which is where I have extracted the downloaded bundle). The problem is, I keep getting an error:
Script error
The path you entered seems valid, but this wizard can't locate the following GTK's include file: gtk.h in it

I have checked and the gtk.h is present in C:\gtk\include\gtk-3.0\gtk

Windows 7 64bit, Code::Blocks 12.11
Does anyone have an idea what am I doing wrong?

Thanks in advance

P.S: I hope this is right section. If not, please move it where it belongs.

Edit: I have edited the GTK+ wizard script and replaced "gtk2.0" with "gtk3.0" where it was necessary and it works, but now when I try to compile the source that I get generated by the Code::Blocks wizard, I keep getting error:
C:\gtk\lib\glib-2.0\include\glibconfig.h|57|error: ISO C90 does not support 'long long' [-Wlong-long]| ||=== Build finished: 1 errors, 0 warnings (0 minutes, 0 seconds) ===|
(which I guess does not belong in this board, but does anyone have an idea what to do with it?)

Used GTK+ 32bit and everything works fine now, just wonder why

Windows and Linux treated 32/64 bit change in different ways; either Windows or the Compiler is NOT doing it the same way as GTK3 expected.

Could also be user error on doing the CB Project settings.

While I was searching for a solution to this exact problem, I never came across a solution...However, I did figure it out myself and it required (After correctly installing GTK+ 3.0 on my system) to edit the GTK+ Project script for Code::Blocks 13.12...I won't rewrite it here but I will give you the link to my post on StackOverflow http://stackoverflow.com/questions/24339805/how-to-fix-the-codeblocks-wizard-to-look-for-gtk-3-0-and-not-2-0/24340596#24340596

Can you provide a diff againts the latest version of this script that is available in trunk?
