From: uwe@thetaphi.de (Uwe Schindler)

The problem is: sfio seems not to be compatible with Solaris 9. The error 
comes from:
#include <stdio-tag.h>
in floatingpoint.h.

This contains only the definition of FILE*... But stdio-tag.tag is not 
included into the sfio package, so
both definitions are different and the compiler do not like it.
I fixed this by creating a sfio-tag.h file in the sfio-include which only 
contains the inclusion of stdio.h
(I think in solaris code the stdio-tag.h file is only for speedup in 
compiling/preprocessing of the internal .h files.

For me it worked then better until a next problem occurs: under solaris 9 
the ranlib tool does not seem to work, so
i have to change the Makefile of sfio to use ar with a parameter instead of 
it. Because the .a file it produces does not
contain symbol information and linking with the sfio-mt.a does not work and 
shows only missing symbols :(

All this is a problem and is not on the PHP side so this is no solution 
until the sfio package is solaris 9 compatible.
