I agree, I'd prefer to use this approach. Two questions though:
1. Since this is just an attribute, the pre-8.1 plugin should just
ignore this. I verified that it does ignore it, but I want to confirm
if I'm understanding it correctly.
2. With 8.1 though, I see an exception generated:
java.lang.IllegalArgumentException: Language Settings Providers must
have unique ID. Duplicate
ID=org.eclipse.cdt.ui.UserLanguageSettingsProvider
at org.eclipse.cdt.internal.core.settings.model.CConfigurationSpecSettings.setLanguageSettingProviders(CConfigurationSpecSettings.java:1030)
at org.eclipse.cdt.internal.core.settings.model.CConfigurationDescription.setLanguageSettingProviders(CConfigurationDescription.java:835)

at org.eclipse.cdt.managedbuilder.ui.wizards.STDWizardHandler.convertProject(STDWizardHandler.java:120)
Could you explain what adding that line actually does? Removing
"org.eclipse.cdt.ui.UserLanguageSettingsProvider" makes it not throw
the exception, but then the indexer isn't resolving headers anymore.
