Description of problem:
the file /usr/include/unixodbc_conf.h contains includes for various architectures, but IA64 is mising

Version-Release number of selected component (if applicable):
unixODBC64-devel-2.2.14-2.el5.ia64

How reproducible:
always

Steps to Reproduce:
1. try to recompile mysql-connector-odbc64
  
Actual results:
configure phase fails

the config.log says:

configure:19969: checking sql.h usability
configure:19981: gcc -c -I/usr/include/mysql -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fno-strict-aliasing -fwrapv -g -O2  -I/usr/include conftest.c >&5
In file included from /usr/include/sql.h:19,
                 from conftest.c:63:
/usr/include/sqltypes.h:56:2: error: #error "Needs to know how big a long int is to continue!!!"


examining sqltypes.h there is:

#ifndef SIZEOF_LONG_INT
#include <unixodbc_conf.h>
#endif

#ifndef SIZEOF_LONG_INT
#error "Needs to know how big a long int is to continue!!!"
#endif


going further to unixodbc_conf.h, you see it is full of arch dependent includes like

#if defined(__x86_64__)
#include "unixodbc_conf_x86_64.h"


but the record for ia64 is missing, despite the file exists:

.qa.[root@ia64-5s-m1 tps]# rpm -qf /usr/include/unixodbc_conf_ia64.h 
unixODBC64-devel-2.2.14-2.el5.ia64



Expected results:
mysql-connector-odbc64 configures and compiles cleanly


Additional info:
note that this may be connected to bug 756832, HOWEVER this does not explain the ppc part of the postgresql problem, as both ppc and ppc64 records are present in that file
