This is something generally better to avoid (because getting a
module configuration from a cycle implies that there can be only
one http{} block), but it is certainly possible to obtain main
configuration via ngx_http_cycle_get_module_main_conf(). For an
example, see ngx_http_perl_init_worker() in the perl module:

http://hg.nginx.org/nginx/file/tip/src/http/modules/perl/ngx_http_perl_module.c#l1041

It is not clear where you get this macro. Defined it yourself?
You certainly did it wrong. Correct macro is defined in
src/http/ngx_http_config.h as follows:

#define ngx_http_cycle_get_module_main_conf(cycle, module) \
(cycle->conf_ctx[ngx_http_module.index] ? \
((ngx_http_conf_ctx_t *) cycle->conf_ctx[ngx_http_module.index]) \
->main_conf[module.ctx_index]: \
NULL)

You don't need to redefine it, just use it as is.
