-----
$ mv lexer.d app.d
$ dmd -I/c/dev/dmd/compiler/src/ app.d

app.d(17): Error: none of the overloads of `this` are callable using argument
types `(string, immutable(char)*, int, ulong, int, int)`
/c/dev/dmd/compiler/src/dmd/lexer.d(111):        Candidates are:
`dmd.lexer.Lexer.this(const(char)* filename, const(char)* base, ulong
begoffset, ulong endoffset, bool doDocComment, bool commentToken, ErrorSink
errorSink, const(char)[] vendor = "DLF", uint versionNumber = 1u)`
/c/dev/dmd/compiler/src/dmd/lexer.d(170):                       
`dmd.lexer.Lexer.this(const(char)* filename, const(char)* base, ulong
begoffset, ulong endoffset, bool doDocComment, bool commentToken, bool
whitespaceToken, ErrorSink errorSink)`
/c/dev/dmd/compiler/src/dmd/lexer.d(182):                       
`dmd.lexer.Lexer.this(ErrorSink errorSink)`

Tried with DMD sources from the last release and also from `master`.
