>Description:
The macro isn't expanded any more. Expected to include file onetwothree.h during compile, but an error is reported:

p.cc:5:16: warning: extra tokens at end of #include directive
p.cc:5:41: one: No such file or directory

With cpp included in gcc 2.95.4 the macro expands correctly.

Synopsis: Macros in #include directive not expanded correctly

State-Changed-From-To: open->closed
State-Changed-By: neil
State-Changed-When: Mon Dec  2 04:30:13 2002
State-Changed-Why:
    Not a bug.  String literal concatenation happens after preprocessing, and therefore after directives have been handled.
