That is the place where we detect EBCDIC. (in build/openldap.m4).
When I am using "CC=cc -K literal_encoding_ascii; export CC ; configure" the 
(pre)compiler handle the 'M' in ASCII therefore EBCDIC is not detected.

Adding a #if !defined(_OSD_POSIX) before include <__ASCII__/generate_error.h> 
solves my problem.
