latest beta code doesn't like this part of jdhuff.c

     /* Section F.2.2.1: decode the DC coefficient difference */

Could you reduce it to a self-contained snippet, please?

I`m also found this trouble :-)

dmc now just does not like constructions:

#define AAA(label) {\
label: \
goto label; \
};

AAA(l1);

which is found in jpeglib.

This works for me:
-----------------------------------------
C:\cbx\ztc>type test.cpp
#define AAA(label) {\
label: \
goto label; \
};

void test()
{
AAA(l1);
}


C:\cbx\ztc>sc -c test

C:\cbx\ztc>obj2asm test
_TEXT   segment dword use32 public 'CODE'       ;size is 2
_TEXT   ends
_DATA   segment dword use32 public 'DATA'       ;size is 0
_DATA   ends
CONST   segment dword use32 public 'CONST'      ;size is 0
CONST   ends
_BSS    segment dword use32 public 'BSS'        ;size is 0
_BSS    ends
FLAT    group
includelib SNN.lib

        public  ?test@@YAXXZ
_TEXT   segment
        assume  CS:_TEXT

This is work for .cpp files and with -cpp compiler option, but not for .c files:

>c:\progs\dm\bin\dmc.exe test.c -c
AAA(l1);
^
test.c(8) : Error: undefined identifier 'l1'
AAA(l1);
^
test.c(8) : Warning 6: value of expression is not used
--- errorlevel 1

Thanks, I have it fixed now. -Walter

thank you, I got the new beta this morning. I'm afraid it now fails with another error, the linker says previous definition different. This did not occur with 8.38

/noi change is not listed in changes at
http://www.digitalmars.com/download/freecompiler.html
so is probably old switch but
http://www.digitalmars.com/ctg/ctgLinkSwitches.html does not list it. There
is /noi switch listed but in http://www.digitalmars.com/ctg/lib.html
What is the rule for /noi switch targeted for future releases?
