[Dovecot] failed dovecot 1.2rc2 build Solaris 8, gcc 2.95.3

[Jernej Porenta]

Hello,

I trying to build dovecot 1.2rc2 on ancient Solaris 8 with gcc 2.95.3 
and it fails with:

configure looks like this:
CPPFLAGS='-I/usr/local/ssl/include -I/opt/kerberos-heimdal/include' 
LDFLAGS='-L/usr/local/ssl/lib -R/usr/local/ssl/lib 
-L/opt/kerberos-heimdal/lib -R/opt/kerberos-heimdal/lib' ./configure 
--prefix=/opt/dovecot --enable-ssl --with-ssldir=/usr/local/ssl/certs 
--with-ssl=openssl --without-passwd-file --with-passwd --with-shadow 
--without-bsdauth --without-static-userdb --without-prefetch-userdb 
--without-checkpassword --with-gssapi=yes --without-pgsql --without-sql 
--without-ldap --without-vpopmail --without-sia

The build goes fine with gcc 3.2.2.

Dovecot 1.1 builds fine with 2.95.3. Are there any requirements for GCC 
version?
