you're correct (see reply from Bruce Evans below) __func__ is
in /usr/src/contrib/gcc/c-common.c
ChangeLog:9854: `__func__'.
c-common.c:164:/* Make bindings for __FUNCTION__, __PRETTY_FUNCTION__, and __func__.
*/
c-common.c:190: declare_hidden_char_array ("__func__", name);
which, if as indicated in ChangeLog:9854

* c-common.c (declare_function_name): Declare predefined variable
`__func__'.
makes me question why the gcc compiler which I believe was
in use for 4.0-CURRENT prior to 21 Jul 99, does not include
the declaration, particularly since the compiler used for
the compile was based on a CURRENT cvsup of 29 Jun 99....
However, that still leaves me between a rock and a hard
spot!
Kernel usage appears limited solely to two error statements
in /usr/src/sys/i386/i386/cksum.c
in_cksum.c:
238 if (len)
239 printf("%s: out of data by %d\n", __func__, len);
426 if (len)
427 printf("%s: out of data by %d\n", __func__, len);
Which is easily enough circumvented (kludged):
238 if (len)
243 printf("%s: out of data by %d\n", "in_cksum", len);
431 if (len)
435 printf("%s: out of data by %d\n", "in_cksum_skip", len);
Which is an abomination... and like Bruce, I question the
need for __func__ at this point...
But, beggars can not be choosers, and, it does compile,
without errors, both GENERIC and the target 'hun'.
And, even better, it appears to execute X from 4.0-CURRENT
along with Xemacs, pine, xshisen (great during long
compiles) etc. --what more could I ask for? Easy, a good
'make world' and update of /etc files. since my cvsup is
from 000422.1619 UCT, maybe JKH's 'BOTD' in netstat.c had
not crept in...

+ __func__ is a new feature in C99. It is an alias for the gcc feature
+ __FUNCTION_NAME. Both give the name of the current function as a string.
+
