xterm fails to compile on Tiger

[jcobleigh]

I tried to compile (and install) the xterm package on Tiger (OS X 10.4). During compilation, I get the following error:

gcc -I. -I. -DHAVE_CONFIG_H -I/usr/X11R6/include

-I/usr/X11R6/include/freetype2 -I/usr/X11R6/include -I/usr/X11R6/include -I. -I/usr/X11R6/include -I/usr/X11R6/include -I/usr/X11R6/include/freetype2 -I./exports/include/X11 -I/usr/X11R6/include -DDARWIN -DNO_ALLOCA -DCSRG_BASED -DXFREE86_FT2 -DUTMP -DOSMAJORVERSION=8 -DOSMINORVERSION=0 -I/usr/X11R6/include -U_XOPEN_SOURCE -D_XOPEN_SOURCE=500 -DPROJECTROOT='"/usr/X11R6"' -Dvendorversion='"Version 4.4.0 XFree86"' -g -O2 -c ./main.c ./main.c: In function 'spawn': ./main.c:3760: error: too many arguments to function 'setpgrp' ./main.c:3762: error: too many arguments to function 'setpgrp' make: * [main.o] Error 1

Line 3760 is: setpgrp(0, 0); Line 3762 is: setpgrp(0, pgrp);

Looking at what the preprocessor generated, it looks like this function is getting defined in /usr/include/unistd.h in an ifdef:

#if DARWIN_UNIX03 pid_t setpgrp(void) DARWIN_ALIAS(setpgrp); #else /* __DARWIN_UNIX03 */ int setpgrp(pid_t pid, pid_t pgrp); /* obsoleted by setpgid() */ #endif /* DARWIN_UNIX03 */

I am not a C expert, but it seems that depending on the value of DARWIN_UNIX03, setpgrp can either take one argument or two arguments. However, I am not sure what is setting DARWIN_UNIX03 and I don't know enough about gcc to get it to tell me this information.
