Architecture: i686

	
host: i686-pld-linux-gnu
build: i686-pld-linux-gnu
target: i686-pld-linux-gnu
configured with: ../configure --prefix=/usr --infodir=/usr/share/info --mandir=/usr/share/man --enable-shared --enable-threads=posix --enable-haifa --enable-languages=c,c++,f77,gcov,java,objc --enable-long-long --enable-namespaces --enable-multilib --with-gnu-as --with-gnu-ld --with-system-zlib --with-slibdir=/lib --without-x i686-pld-linux
>Description:
	When my code snippet is compiled without the -O switch, gcc compiles
	the file corectly, and the program runs correctly.
	When compiled with the -O switch, gcc complains about conflicting types
	for built-in function `fprintf'.
>How-To-Repeat:
	Preprocessor output is appended here.
	Compiles with:		gcc -o try try.c
	But not with:		gcc -O -o try try.c

	When the -O switch is used, gcc converts printf(...) to
	fprintf(stdout, ...) which may not always be appropriate.

>Fix:
	Do not use -O switch for this code.
