I have just installed gcc 2.4.5 on my Sparc 2 running sunos 4.1.3.
Everything seemed to go well, but when I compile a simple hello.c
file with
	gcc -Wall -o hello hello.c
I get
	hello.c: In function `main':
	hello.c:5 warning: implicit declaration of function `printf'
	hello.c:5 warning: implicit declaration of function `puts'

The file hello.c is
-----------------
#include <stdio.h>

int main(void)
{
  printf("Hello, world.\n");
  puts("Hello, world.\n");
  
  return(0);
}
-----------------
The compiled program works fine.  But I found that the stdio.h file
that gcc created does not have a printf or sprintf function prototype,
ditto for puts.  I also found this to be the case for gcc installed
on several other suns.  I am worried about these missing, and many
other (!), prototypes.

It seems to me this is a problem.  Can anyone help me out, especially
Sparc 2 users?

Here is a summary of my install procedure, which went smoothly.
    36	configure --target=sparc-sun-sunos4.1.3
    37	make LANGUAGES=c
    38	make stage1
    39	make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O" LANGUAGES=c
    40	make stage2
    41	rm -rf stage1
    42	make CC="stage2/xgcc -Bstage/" CFLAGS="-g -O" LANGUAGES=c
    43	pwd
    44	make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O" LANGUAGES=c
    45	make compare
    46	make install CC="stage2/xgcc -Bstage2/" CFLAGS=-g -O" LANGUAGES=c
    47	make install CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O" LANGUAGES=c

Line 46 was just a typo.
