Version:           Gideon 3.0.0a4 (using KDE KDE 3.1.1)
Installed from:    Gentoo Packages
Compiler:          gcc 3.2.2 
OS:          Linux

From main menu with a C++ project, do the following:

Project --> Project Options --> Configure Options --> C++ --> [...] on the Compiler Flags line.

In the General tab, enable the 'Enable exception handling' feature in Code Generation.

Expected result:
-fexceptions would be added to the compiler options.

Alternate expected result:
-fno-exceptions, if it exists in the compiler options textbox, would be removed.

Actual result:
Although nothing to do with -f{no-,}exceptions exists in the compiler options textbox, -fno-exceptions is added.  This DISABLES rather than enables exception handling using g++.

Suggested solution:
Change the behavior.  Make it add -fexceptions instead of -fno-exceptions.  Alternatively, change the wording to 'Disable exception handling', though this wording is rather nasty.
