OpenLdap libraries under SCO OpenServer 3.2v4

[ablancho@gfi.fr]

I ve got problems when trying to compile OpenLdap libraries (1.2.9 release)
under SCO Openserver
3.2v4 :

    1) the error message, on all openldap-1.2.9/libraries/*.c is :
    /usr/include/sys/time.h(35): error C2011 : 'timeval' : type type
redefinition

    2) i have also the following error  when i compile dsparse.c :
    /usr/include/sys/file.h(55): error C2061  : Syntax error : identifier
'ushort'

I think i don't use ./configure with the right option, but what i have to do to
resolve these problems ?
