Use the official _BSD_SOURCE feature test macro instead of the meaningless
|
HAVE_STRSEP macro in order to detect the availability of strsep().
|
|
This allows toolchains supporting strsep() to use it instead of the custom
|
implementation from dhcpdump, which also avoids the following error with some
|
toolchains:
|
|
In file included from dhcpdump.c:30:0:
|
dhcpdump.c: At top level:
|
strsep.c:65:23: error: register name not specified for ‘delim’
|
register const char *delim;
