Do not ship evconfig-private.h in dist archive It will be generated by autotools, so there is not reason to include it. And infact this breaks compilation with out-of-tree builds (VPATH), since, for the quote form of the include directive, headers in the directory of the file with the #include line have priority over those named in -I options, the copy of evconfig-private.h from the source directory had priority over the one in the build directory.
