after Config I executed "make" line command and I can see the following errors:
chanserv.c: In function âload_cs_dbaseâ:
chanserv.c:451: warning: ignoring return value of âfreadâ, declared with attribute warn_unused_result
chanserv.c:484: warning: ignoring return value of âfreadâ, declared with attribute warn_unused_result

chanserv.c:889: warning: ignoring return value of âfwriteâ, declared with attribute warn_unused_result
chanserv.c:946: warning: ignoring return value of âfwriteâ, declared with attribute warn_unused_result
What means this?
