Hello All,
OK, I tried to compile libstdc++-2.90.8 with gcc-2.95.2 and I get:

c++io.cc: In method `struct __c_streampos __basic_file::seekoff(long int, _Ios_Seekdir, _Ios_Openmode = operator |((enum _Ios_Openmode)1, (enum _Ios_Openmode)2))':
c++io.cc:210: conversion from `__off64_t' to non-scalar type `__c_streampos' requested

c++io.cc:243: warning: control reaches end of non-void function `__basic_file::sys_seek(_G_fpos64_t, _Ios_Seekdir)'
make[4]: *** [c++io.lo] Error 1

And I think it is related to glibc-2.2.

I found that __c_streampos is defined as the old _fpos_t:

libstdc++-v3/config/c_io_libio.h:47:  typedef _IO_fpos64_t  __c_streampos;
libstdc++-v3/config/c_io_libio.h:49:  typedef _IO_fpos_t    __c_streampos;

So I changed it with the following patch:

--- c_io_libio.h.ezz    Fri Mar  9 14:27:22 2001
+++ c_io_libio.h        Fri Mar  9 14:28:39 2001

   typedef _IO_ssize_t  wstreamsize;
 #endif
 #if defined(_G_IO_IO_FILE_VERSION) && _G_IO_IO_FILE_VERSION == 0x20001
-  typedef _IO_fpos64_t  __c_streampos;
+  typedef _IO_off64_t  __c_streampos;
 #else
-  typedef _IO_fpos_t    __c_streampos;
+  typedef _IO_off_t    __c_streampos;
 #endif

   typedef _IO_lock_t   __c_lock;

So the compiler does not complain about the __c_streampos
anymore. However, now I get the errors below. I will get the 2001-01-22
GCC 3.0 snapshot and try to compile. Please help me find some reliable
environment for compiling some ported code that uses STL with name
spaces.
