[pgadmin-support] Build wxWidgets-2.8.0 in Cygwin

[QuanZongliang]

hi!
 
I had compiled wxWidgets-2.8.0 in Cygwin with command:
    ./configure --with-gtk --enable-gtk2 --enable-unicode --enable-mimetype=no
but got warning message:
    checking for backtrace() in <execinfo.h>... no    configure: WARNING: 
backtrace() is not available, wxStackWalker will not be available
 
Can the pgAdmin be built without wxStackWalker?
How to correct it?
 
Thanks
Quan
