nonstandard assumptions in the code
I've been getting a bit nervous lately about the number of non-ANSI
assumptions which the OpenLDAP code makes. I'd like to at least write a
test program which configure can run and which tries to warn if one of
the assumptions do not hold.
Here are the nonstandard assumptions I have found. Do anyone know any
* two's complement integers
* at least 4-byte 'int'
* 8-bit 'char'
* ASCII or EBCDIC character set (or a superset of these)
(basic assumptions, leave these alone)
* no padding bits in 'unsigned int'
(required by back-bdb/dbcache.c:bdb_db_hash() - don't know why)
* can cast 'int' to 'void *' and back
(at least back-shell)
* can cast function pointers to 'void *' and back
(at least the threading stuff)
* can meaningfully compare pointers to different malloced blocks
* 'long long' support
(liblutil/uuid.c - can write #ifndef HAVE_LONG_LONG variant to fix it)
* accepts string literals longer than 509 characters
(easy to fix)
* other limits, like lower max num of #defines
(leave these alone)
One other question - how do I test whether the ldap installation will
support EBCDIC? I know EBCDIC support has been added, or at least is
partly added, but I don't know how to test for it in configure.
