Re: glibc related porting questions

[Roland McGrath]

The same thing came up for Ruby.  There ought to be a stdio_ext.h interface
for this.

You can change that code to:

#if defined(__GLIBC__) && defined(_STDIO_USES_IOSTREAM)
   if (f->_IO_read_ptr < f->_IO_read_end)
      RetArg(1);
#elif defined(__GLIBC__)
   if (f->__bufp < f->_get_limit)
      RetArg(1);
