building Lighttpd 1.4.30 using gcc 4.4.6: ___builtin_stdarg_start referenced

Show all headers | View raw

Greetings, all...

It would surely be more fun building things if I could actually get 
something to work every now and again. ;-) If I couldn't do this on 
Linux with some success, I would probably chalk it up to my own lack of 
ability. Anyway...

Trying to build the above, running make, I get:

lemon.c: In function 'ErrorMsg':
lemon.c:1305: warning: implicit declaration of function 
'__builtin_stdarg_start'

lemon.c:1305: warning: 'ap' is used uninitialized in this function
mv -f .deps/lemon.Tpo .deps/lemon.Po
ash.exe ../libtool  --tag=CC   --mode=link gcc  -g -O2 -Wall -W -Wshadow 
-pedant
ic -std=gnu99   -o lemon.exe lemon.o
libtool: link: gcc -g -O2 -Wall -W -Wshadow -pedantic -std=gnu99 -o 
lemon.exe le
mon.o
lemon.c:1305 (lemon.o): Undefined symbol ___builtin_stdarg_start 
referenced from
  text segment
gcc: Internal error: Hangup (program ld.exe)

My reading of some gcc info tells me that ___builtin_stdarg_start was 
deprecated by 2008 or so (see 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35460), and in fact, line 
1305 of lemon.c references va_start:

   va_start(ap, format);
   /* Prepare a prefix to be prepended to every output line */
   if( lineno>0 ){
     sprintf(prefix,"%.*s:%d: ",PREFIXLIMIT-10,filename,lineno);
   }else{
     sprintf(prefix,"%.*s: ",PREFIXLIMIT-10,filename);
   }
   prefixsize = strlen(prefix);
   availablewidth = LINEWIDTH - prefixsize;

   /* Generate the error message */
   vsprintf(errmsg,format,ap);
   va_end(ap);
   errmsgsize = strlen(errmsg);
   /* Remove trailing '\n's from the error message. */
   while( errmsgsize>0 && errmsg[errmsgsize-1]=='\n' ){
      errmsg[--errmsgsize] = 0;
   }

I've tried this both with Paul's packaged gcc446 (and the included 
gcc446.cmd, edited to reference j: instead of u:, to fit my setup), and 
with the 4.4.6 build installed via yum (which was no mean feat, as 
"/usr/lib/libiberty.a from install of gcc-4.4.6-11.oc00.i386 conflicts 
with file from package binutils-static-2.21-1.oc00.i386" - I finally 
forced it).

Anyway, I get the same stall using either gcc 4.4.6. Is 
___builtin_stdarg_start defined (incorrectly) somewhere?

TIA
