Older versions of GCC have trouble building ide/Debuggers/Gdb_MI2.cpp after recent changes in ide.h, introduced in r7461:

[  830s] In file included from /usr/src/packages/BUILD/uppsrc/ide/Debuggers/Gdb_MI2.cpp:2:0:
[  830s] uppsrc/ide/ide.h:1065:20: error: declaration of 'void Ide::Display()' [-fpermissive]

[  830s] uppsrc/Draw/Display.h:1:7: error: changes meaning of 'Display' from 'class Upp::Display' [-fpermissive]

It fails on almost all the platforms for which I create packages, with exception of Arch where the GCC is version 4.9. Versions 4.4 and 4.7 do not work.
