[Bug c++/20259] New: iostream functions/methods declared

["ramya dot chandar at wipro dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Environment     : i686-pc-linux-gnu
Compiler Version: GCC 3.3.2 
Kernel Version  : 2.4.7-10

I am compiling a "String.cc" file. It is giving the below given error.

But, I could see the ipfx function being defined in 'iostream.h" and the
"iostream.h" is being included in the corresponding header file "String.h"

======== Rebuilding "String.o" ========
        /cm4/tools/GNU/src/gcc/Linux_2.4.7-10/bin/g++ -DHOST_ARCH_LINUX

-fpermissive -Wno-deprecated -c String.cc -o String.o

String.cc: In function `std::istream& operator>>(std::istream&, String&)':
String.cc:1195: error: `ipfx' undeclared (first use this function)
String.cc:1195: error: (Each undeclared identifier is reported only once for 
   each function it appears in.)
String.cc:1217: warning: invalid conversion from `int' to `std::_Ios_Iostate'
String.cc:1217: warning:   initializing argument 1 of `void 
   std::basic_ios<_CharT, _Traits>::clear(std::_Ios_Iostate) [with _CharT = 
   char, _Traits = std::char_traits<char>]'
String.cc: In function `int readline(std::istream&, String&, char, int)':
String.cc:1223: error: `ipfx' undeclared (first use this function)
*** Error code 1
clearmake: Error: Build script failed for "String.o"
========================================================

And I could see, the ipfx function is being optimized in iostream.h. Is that
creating the problem.

Any idea, Why this problem is happening with GCC 3.3.2. 

NOTE: I am able to compile the same code with GCC 2.95.3
