Make errors

["Greene, Joe" <joe.greene@xxxxxxx>]

After modifying the Makefile for the root of the XSscroch to get past this
error:
gcc -DHAVE_CONFIG_H -I. -I. -I. -Isgame -Isgtk    -g -O2 -c xscorch.c
xscorch.c: In function `main':
xscorch.c:77: union has no member named `_sigaction'
*** Error code 1
make: Fatal error: Command failed for target `xscorch.o

I rerun make and get the below error, which I do not know the fix for. Any
suggestions? (note I had to add -D_POSIX_C_SOURCE=3 to get around the
_sigaction error above)
