"gai.h" not found during compilation [patch]

[Paul Boven]

Hi everyone,

While trying to build Cyrus-imapd-2.2.12, compilation stops almost 
immediately because "gai.h" cannot be found.

I'm using these arguments to configure my cyrus-imapd:

ac_cv_lib_socket_getnameinfo=no ac_cv_func_getnameinfo=no ./configure 
--with-perl=/bin/perl --with-sasl=/usr/local 
--with-cyrus-prefix=/usr/local/cyrus 
--with-dbdir=/usr/local/BerkeleyDB.4.1 --with-auth=unix 
--with-openssl=/usr/local

The build environment is a Solaris 9 Ultra-Sparc machine.

The first two entries are to prevent a lot of error messages because 
apparently cyrus doesn't like the Solaris getnameinfo.

This then causes "gai.h" to be included. But gai.h lives in 
cyrus-imapd-2.2.12/lib/gai.h and cannot be found. I assume this include 
is being triggered only in my builds because of the way I run configure.

### Making all in /export/home/boven/cyrus-imapd-2.2.12/lib
make[1]: Entering directory `/export/home/boven/cyrus-imapd-2.2.12/lib'
./../tools/config2header CC=gcc ./imapopts.c ./imapopts.h < ./imapoptions
gcc -c -I.. -I/usr/local/BerkeleyDB.4.1/include  -I/usr/local/include 
-I../et -I/usr/local/include -DHAVE_CONFIG_H  -g -O2  \
libconfig.c
In file included from libconfig.c:44:
../config.h:429:17: gai.h: No such file or directory

My solution: when building the files in cyrus-imapd-2.2.12/lib, make 
sure that the directory in question is being included by adding a -I. to 
the CPPFLAGS.
By the way, I don't think that '-I..' really needs to be set in that 
Makefile because that includes the top-level cyrus-directory which
doesn't contain any include-files.

Suggested patch:
