Subject: Link error of "mcnaf" 
I repeated the link error again. I also found the almost all sources located in "driver/camac/" using "cam_op()" but not "camop()". Please see the grep result below:
drivers/camac/camaclx.c:760:INLINE void cam_op()
drivers/camac/camacnul.c:200:INLINE void cam_op()
drivers/camac/camacrpc.c:563:void cam_op()
drivers/camac/cc7700pci.c:744:INLINE void cam_op()
drivers/camac/ces2117.c:227:void cam_op()
drivers/camac/ces8210.c:553:void cam_op(void)
drivers/camac/ces8210.c:576:    cam_op();
drivers/camac/ces8210.c:625:    cam_op();
drivers/camac/dsp004.c:692:void cam_op()
drivers/camac/hyt1331.c:1125:INLINE void cam_op()
drivers/camac/jorway73a.c:563:INLINE void cam_op()
drivers/camac/kcs2926.c:618:INLINE void cam_op()
drivers/camac/kcs2927.c:677:INLINE void cam_op()
drivers/camac/wecc32.c:554:INLINE void cam_op()

I also found why the default Makefile can pass away this problem. I found the "make" using the following command to compile the "mcnaf":
cc -g -O3 -Wall -Wuninitialized -Iinclude -Idrivers -I../mxml -Llinux/lib -DINCLUDE_FTPLIB   -D_LARGEFILE64_SOURCE -DHAVE_MYSQL -I/usr/include/mysql -DHAVE_ODBC -DHAVE_ZLIB -DOS_LINUX -fPIC -Wno-unused-function -o linux/bin/mcnaf utils/mcnaf.c drivers/camac/camacrpc.c linux/lib/libmidas.a -lutil -lpthread -lodbc -lz
I try to re-implement the link error again. So I wrote some test code.

1. anullf.h
#ifndef _ANULLF_H_
#define _ANULLF_H_ 1

#define EXTERNAL extern

#if defined( _MSC_VER )
#define INLINE __inline
#elif defined(__GNUC__)
#define INLINE __inline__
#define INLINE
/* make functions under WinNT dll exportable */
#if defined(_MSC_VER) && defined(MIDAS_DLL)
#define EXPRT __declspec(dllexport)
#define EXPRT

EXTERNAL INLINE void EXPRT camop() {  };


2. ma_1.c
#include "anullf.h"

void cam_op() {}

3. ma.c
#include "anullf.h"
#include <stdio.h>

int main(int argc, char** argv)

Then, only compiling as below can pass:
$ gcc -O -o ma ma_1.c ma.c
If you remove the option "-O", compiling immediately fails in a link error. Whether you compile into objects then link them or just compile them together, you can pass with option "-O" or the similar options. It is because the compile could solve linking to a dummy function automatically with option "-O".

Anyway, we should fix this no matter changing the "mcstd.h" or codes located in "driver/camac/".
