 Hello,
 
 what's the current status of this bug? The report hasn't been updated  
 since May 3, 2002, when Ben said he was going to take care of it. Is  
 the problem in this report still present? If so, is anyone working  
 fixing it? Thanks,
 
 Dara

>Environment:
sparc-sun-solaris2.7
>Description:
when _FILE_OFFSET_BITS is set to `64', the system's stdio.h will actually make the symbols fopen, freopen, tmpfile, fgetpos and fsetpos unavailable at all, even as normal function definitions, if they are #undef'd.  This causes the later part of the header file pulling these into namespace std to fail with complaints these symbols are undefined.
>How-To-Repeat:
attempt to build Berkeley db-3.3.11 after passing --enable-cxx to the configure script.
>Fix:
This is probably not the best fix, but it got me past the issue.  Somebody who knows their way around the solaris headers better than I do could probably come up with a more "real" fix:

in $prefix/include/g++-v3/bits/std_cstdio.h, remove the #undef macros for these symbols, and add the following code at line 43 (right after #include <stdio.h>):

// The following functions _can not_ be #undef'd if we are using 64
// bit file pointers
#if ! (defined (sun) && !defined (_LP64) && _FILE_OFFSET_BITS == 64)

#undef fopen
#undef freopen
#undef tmpfile
#undef fgetpos
#undef fsetpos

#endif // whew
