dnl If KRB5_CPPFLAGS, KRB5_LDFLAGS, or KRB5_LIBS are set before calling these
dnl macros, their values will be added to whatever the macros discover.
dnl
+dnl KRB5_CPPFLAGS_GCC will be set to the same value as KRB5_CPPFLAGS but with
+dnl any occurrences of -I changed to -isystem. This may be useful to suppress
+dnl warnings from the Kerberos header files when building with GCC and
+dnl aggressive warning flags. Be aware that this change will change the
+dnl compiler header file search order as well.
+dnl
dnl Provides the RRA_LIB_KRB5_OPTIONAL macro, which should be used if Kerberos
dnl support is optional. In this case, Kerberos libraries are mandatory if
dnl --with-krb5 is given, and will not be probed for if --without-krb5 is
dnl probing the Kerberos library properties.
