67 Instead of using EV_STANDALONE=1 and providing your config in whatever
68 way you want, you can also m4_include([libev.m4]) in your configure.ac
69 and leave EV_STANDALONE off. ev.c will then include "config.h" and
70 configure itself accordingly.

144 reserved for future expansion, works like the USE symbols above.
145
146 EV_H
147
148 The name of the ev.h header file used to include it. The default
149 if undefined is <ev.h> in event.h and "ev.h" in ev.c. This can
150 be used to virtually rename the ev.h header file in case of
151 conflicts.
152
153 EV_EVENT_H
154
155 Similarly to EV_H, this macro cna be used to override event.c's idea
156 of how the event.h header can be found.
157
158 EV_PROTOTYPES
159
160 If defined to be "0", then "ev.h" will not define any function
161 prototypes, but still define all the structs and other
162 symbols. This is occasionally useful.
163
164 EV_MULTIPLICITY
165
166 If undefined or defined to "1", then all event-loop-specific
167 functions will have the "struct ev_loop *" as first argument, and
168 you can create additional independent event loops. Otherwise there
169 will be no support for multiple event loops and there is no first
170 event loop pointer argument. Instead, all functions act on the
171 single default loop.
172
173 EV_PERIODICS
174
175 If undefined or defined to be "1", then periodic timers are
176 supported, otherwise not. This saves a few kb of code.

151 198 the ev.v header file for their default definitions. One possible
152 EV_MULTIPLICITY 199 use for overriding these is to avoid the ev_loop pointer as first
153 200 argument in all cases, or to use method calls instead of plain
