# Until bug #537330 glib is a reverse dependency of pkgconfig and, then
# adding new dependencies end up making stage3 to grow. Every addition needs
# then to be think very closely.

EAPI="5"
PYTHON_COMPAT=( python2_7 )
# Building with --disable-debug highly unrecommended.  It will build glib in
# an unusable form as it disables some commonly used API.  Please do not
# convert this to the use_enable form, as it results in a broken build.
GCONF_DEBUG="yes"
# Completely useless with or without USE static-libs, people need to use
