#2876: Inconsistent error message
-----------------------------+----------------------------------------------
Reporter: guest | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.10.1 | Severity: normal
Keywords: | Testcase:
Os: Unknown/Multiple | Architecture: Unknown/Multiple
-----------------------------+----------------------------------------------
Most error messages mention language extensions needed, this one mentions
a deprectaed flag:
{{{
Illegal instance declaration for `...'
(the Coverage Condition fails for one of the functional
dependencies;
Use -fallow-undecidable-instances to permit this)
}}}
It should instead mention -XUndecidableInstances.
