Squid-2.0.RELEASE compile error with Solaris 2.6

Hi,

I am using a Sun Ultra 1 with Solaris 2.6 with Sunsolve Patches
September 1998,
gcc version 2.7.2.2 and GNU make.

After having entered "./configure --prefix=/opt/squid"
and "make all" I receive the following error messages:

gcc -g -O2 -Wall -I. -I../include -I../include -c debug.c
debug.c: In function `_db_print':
debug.c:65: `__builtin_va_alist' undeclared (first use this function)
debug.c:65: (Each undeclared identifier is reported only once
debug.c:65: for each function it appears in.)
debug.c:50: warning: `args' might be used uninitialized in this function

debug.c: In function `debugArg':
debug.c:119: warning: implicit declaration of function `strncasecmp'
make[1]: *** [debug.o] Error 1
make[1]: Leaving directory `/opt/squid/src/squid-2.0.RELEASE/src'
make: *** [all] Error 1

I have looked through the mailing archive but have not found anything.
Has anybody got an idea what I can do?

Thanks in advance.

Sincerely
Dieter Laube
