Bugzilla Bug 99582

When I try to emerge gnome-session-2.10.0-r2 with useflags +esd +ipv6, it gives
a syntax error during the configuration step, hence aborting the comilation fo
the package.

Reproducible: Always
Steps to Reproduce:
1. echo gnome-base/gnome-session -debug -doc esd ipv6 >> /etc/portage/package.use
2. emerge gnome-session


Actual Results:  
The emerge stops at the configuration step giving this error:
./configure: line 21194: syntax error near unexpected token `yes'
./configure: line 21194: `GNOME_COMPILE_WARNINGS(yes)'
and then aborts (correct behaviour)

Expected Results:  
Completed the configuration step and proceeding to compile the package
