compiler warning compiling dgif_lib.c

Wednesday, 2 September 1998


        On solaris 2.5.1, /usr/include/stdio.h I have:

...
 /*
  * The following are known to POSIX and XOPEN, but not to ANSI-C.
  */
 #if defined(__EXTENSIONS__) || __STDC__ == 0 || \
 		defined(_POSIX_C_SOURCE) || defined(_XOPEN_SOURCE)
 
 extern FILE	*fdopen(int, const char *);
 extern char	*ctermid(char *);
 extern int	fileno(FILE *);
 
 #endif	/* defined(__EXTENSIONS__) ||  __STDC__ == 0 ... */ 
which results in the following warning:

...
 gcc -c -Wall -g -O2 -msupersparc  -Demacs -I. -DHAVE_CONFIG_H
-I/proj/mstar/software/install/include -I/usr/dt/include -I/usr/openwin/include
dgif_lib.c
 dgif_lib.c: In function `DGifOpenFileHandle':
 dgif_lib.c:81: warning: implicit declaration of function `fdopen'
 dgif_lib.c:81: warning: assignment makes pointer from integer without a cast 
What's the right way to get fdopen declared for XEmacs?
Since int and pointer are both 32 bit this won't actually 
cause a problem, but it should be fixed.
