Bug #: 52485
Summary: [c++11] add an option to disable c++11 user-defined
literals
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: e...@doxos.eu
Some upstream code (e.g. #50917 for Mozilla, I have issues with Qt4's SLOT(...)
macros) is broken because of the support for c++11 literals in 4.7. In all
cases I've seen the cause was missing space between constructs like #define
FOO(a) "0"#a.
Sine this feature is little used, but lot of code, it would be reasonable to
provide a switch to disable user-defined literals, so that code which needs
c++11 but at the same time links to (technically broken) libs can be compiled,
until those libs get fixed upstream.
