I am posting this here, because the problem I raised in the Help forum, may need to be attended by some of the Admin of the site.
In the distribution of the C::B 12.11 for Windows .. 7, there seem to be at least two problems to check out, IMHO :
1) in the global 'Settings/Compiler Settings/other options' the distiruted program for the 'codeblocks-12.11mingw-setup.exe', some one has left in '-Wc++0c=compat', which caused my problem.
2) While you claimed that codeblocks-12.11mingw-setup_user.exe would install without Administrator permission, I found that it did not, but codeblocks-12.11mingw-setup.exe did, without intervention.
