Just miscellaneous stuff related to cygwin.

How to create a shortcut in cygwin environment for easy package upgrade setup access:

$ echo "run.exe /cygdrive/c/LOCATION/TO/THE/INSTALLATION/setup-x86_64.exe -B" > ~/cygupdate
$ chmod +x ~/cygupdate

$ ~/cygupdate

Xchat gave the following error while compiling: "error: #error "Only <glib.h> can be included directly."

In order to fix this error, you need to execute this command in the xchat's source directory:
$ sed -i 's|<glib/.*\.h>|<glib.h>|' src/common/{servlist.c,text.c,util.c,xchat.h}
