Query about gcc 3.4.3 in relation to include file "<varargs.h> "

[Sandeep Mane <sandeep@xxxxxxxxxxx>]

Hi,

We had the following query about gcc 3.4.3

Problem:  Compilation failure due to difference in include files  : 
<varargs.h> , <stdargs.h> . The OS is RHEL 4.0 and compiler is gcc 3.4.3
Failure log:
*******
gcc -c -g -I. -I. -DHAVE_UNISTD_H=1 -DNEED_MATHERR=1     
-DTCL_LIBRARY=\"/qa_builds/vdsmainrhel40d_snv/tcl/7.3/Linux_2.4.21-27.0.2.EL_32bit/dbg/lib/tcl\" 
tclBasic.c
tclBasic.c:1249: error: syntax error before "va_dcl"
tclBasic.c:1250: error: syntax error before '{' token
tclBasic.c:1266:21: macro "va_start" requires 2 arguments, but only 1 
given" etc.
*******

Details:   We have a  code that has reference to  "va_dcl"  that was 
defined in  compiler include file: "varargs.h".   As we migrated from 
gcc 3.2.3 to gcc 3.4.3 we found that the  compiler 3.4.3 does not 
support "<varargs.h>".   And  "stdargs.h" also does not seem to define 
"va_dcl" .

Is there any patch / workaround/ option available for this compatibility 
issue for  "varargs.h" and "stdarg.h"?
Any pointers will be appreciated.

Thanks ,
Sandeep
