--- Comment #3 from Andrey Ponomarenko <aponomarenko at rosalab dot ru> --- Please do not remove this option! I know that it's private option for debugging GCC only, but it's used in the ABI Compliance Checker tool: http://ispras.linuxbase.org/index.php/ABI_compliance_checker This tool is used by the army of maintainers of almost all Linux distributions to verify ABI changes in system libraries. The tool is also the core of the http://upstream-tracker.org/ service for tracking upstream changes in APIs of system libraries. If you remove this option then ABI Compliance Checker and upstream-tracker.org will stop working and DLL hell will return. Is there an alternative way to create translation unit dump of the header file by the new GCC 4.8? Is it possible to make this option working like in GCC<=4.7? Thank you!
