Comment (by pdziepak):

 The problem with Quake II is that the runtime loader correctly sets
 `ref_soft.so_seg0ro` protection to read and execute but then Quake II sets
 its protection to read and write (i.e. in an attempt to make it writable
 it makes it non-executable).

 Disabling DEP might indeed be a good solution. Since we have the comfort
 of having `libroot` I do believe the best way to do this would be to sete
 `B_EXECUTE_AREA` for all areas that are created (or have their protection
 modified) by applications that the runtime loader recognizes as
 `B_HAIKU_ABI_GCC_2_BEOS`.
