NetBSD compile error

[Austin English]

I just installed NetBSD 5.0RC4 on a spare hard drive, and tried
compiling Wine. I hadn't seen this error before, but I'm not sure if
the regression is on NetBSD or Wine's end.

Google doesn't show too much for this error, other than that
apparently NetBSD's libexec requires execname to not be NULL:
	case 2:	/* ORIGIN */
		if (execname == NULL)
			xerr(1, "execname not specified in AUX vector");
		if ((ep = strrchr(p = execname, '/')) == NULL)
			xerr(1, "bad execname `%s' in AUX vector", execname);
		break;

austin987$ make
LD_LIBRARY_PATH="../../libs/wine:$LD_LIBRARY_PATH" ../../tools/wrc/wrc
--nostdinc -I. -I. -I../../include -I../../include  -D__WINESRC__
-D_ADVAPI32_  -foversion.res version.rc
execname not specified in AUX vector: No such file or directory
*** Error code 1

Can anyone shed some light on this error?
