From 27ddcd48c1091a9aa1090d2506e04a2b75ed0ae3 Mon Sep 17 00:00:00 2001 From: Benjamin Kosnik Date: Thu, 23 Nov 2000 03:25:47 +0000 Subject: [PATCH] Make deprecated strstream header consistent with new and new.h. 2000-11-22 Benjamin Kosnik Make deprecated strstream header consistent with new and new.h. * include/backward/strstream.h: Add. Use using declarations to scope strstreambuf, istrstream, ostrstream, strstream to global scope. * include/backward/strstream: Remove using declarations. * src/Makefile.am (base_headers): Add strstream. * src/Makefile.in: Regenerate. * include/backward/new.h (_CPP_BACKWARD_NEW_H): Change macro guard to be consistent with other headers.
