Compiling Glib 2.16.5 on strawberry perl

[RAPPAZ Francois <francois rappaz unifr ch>]

I fetched the Gtk+ stack from http://ftp.gnome.org/pub/GNOME/binaries/win32/gtk+ (Bundle 2.24) that I 
unzipped in C:\prog\gtk+ 

My %path% contains C:\strawberry\c\bin;C:\strawberry\perl\site\bin;C:\strawberry\perl\bin;C:\prog\gtk+\bin 
My PKG_CONFIG_PATH is C:\strawberry\c\lib\pkgconfig; C:\prog\gtk+\lib\pkgconfig 

I'm trying to compile Glib-2.0 ver 2.16.5 The linker fails with
 
 "C:\strawberry\perl\bin\perl.exe" -MExtUtils::Command::MM -e cp_nonempty -- Glib .bs 
blib\arch\auto\Glib\Glib.bs 644 [ LD blib\arch\auto\Glib\Glib.xs.dll ] Cannot export SvGVariant: symbol not  
defined ...

My makefile is done with

perl Makefile.pl INC="-IC:\prog\gtk+\include\glib-2.0 -IC:\prog\Gtk+\lib\glib-2.0\include -I. -./build" 
LIBS="-LC:/prog/gtk+/lib -lglib-2.0 -lintl -lgobject-2.0 -lgthread-2.0"

Thanks for any help
