You need to look at the complete output of nmake to find where the 
earlier errors are that caused this.

The compiler is too dumb to know that abort never returns.

This is not a real problem since the undefined value of consumed_chars
is not used for anything else.

Again, xsignal1 never returns.

    The compiler is too dumb to know that abort never returns.

Maybe abort needs one more nickel in order to return.

:-)

(sorry for replying to this mail instead of Andreas' or Christoph's,  
but I just joined this list, don't have all of their original mails/ 
postings and my stupid news server won't let me post to  
gnu.emacs.bug :-()

Anyway, process.h and stdlib.h of the old Mickeysoft DevStudio 6.0  
SP6 both contain

    #if _MSC_VER >= 1200
    _CRTIMP __declspec(noreturn) void __cdecl abort(void);

so your compiler *should* know better. At least he can't blaim it on  
the header files ;-).
(_MSC_VER=1200 is the Visual C++ 6.0 compiler, and your's is newer)
If your header files contain the same __declspec(noreturn), I'd say  
the compiler is talking about an other path of control not involving  
abort().

Have a nice day,
Tobias

PS: Please get the english version of DevStudio next time, the german  
translations of some error messages are plain stupid... or feed them  
to babelfish before posting ;-).

Hi Tobias,

> PS: Please get the english version of DevStudio next time

Sure - i did not order that version and forget to mention i want the
english version. Afterwards you cannot switch the german version to the
english version, i asked microsoft support.

> the german translations of some error messages are plain stupid

Agreed.

With kind regards,
Christoph

It is clear that the warnings don't stop the make process. I did not see
any error, but obviously i have overlooked an error. Will do again on
monday (windows only in the company).

With kind regards,

Is that a warning or an error? The resource compiler shouldn't really 
care about the contents of the icon, it should just do as it is told and 
include it as a resource.

We can probably work around this. msvc appears to have floor and ceil, 
just not an equivalent of round or rint.

I agree, it should be a warning, but it is an error, saying "old DIB in
res\main.ico; pass it through SDKPAINT". According to a search with
google you need a "vista-aware" resource compiler. Removing the
compression from the icon made it acceptable to the visual studio 2003
resource compiler.

Yes, at least with visual studio 2003.
