Five modules which define optional functions do not have header files installed on Windows. They are: mod_cache.h mod_dbd.h mod_log_config.h mod_rewrite.h mod_ssl.h This prevents using the APR_OPTIONAL_FN_TYPE macro with these modules' optional functions. The other five modules with optional functions are correctly installed: mod_cgi.h mod_core.h mod_dav.h mod_include.h mod_proxy.h mod_so.h This is only a problem with Windows installs. A patch is provided for libhttpd.dsp which adds the missing headers to the project and copies them to .\include with a custom build step, like the correctly installed headers.
Created attachment 21054 [details] patch to libhttpd.dsp (Windows) for missing headers
mod_status.h is also a missing header on Windows, isn't it? < Bug 34092 >
on Unix at least these are missing: mod_cache.h mod_rewrite.h mod_so.h
and mod_authz_dbd.h ?
one bug per header is overkill *** This bug has been marked as a duplicate of 34092 ***
