How to compile with 32bit arch on 64bit machine:

1) set the PAM_BIT environmental variable to "-m32"

2) enter the directory "event" 

3) mv Makefile Makefile.orig

4) mv Makefile.compile32biton64bitarch Makefile

5) edit Makefile and set the correct path for these two lines, repeated twice on lines 103/104 and 117/118 

       /usr/lib/gcc/x86_64-redhat-linux/3.4.6/32/crtbeginS.o \
       /usr/lib/gcc/x86_64-redhat-linux/3.4.6/32/crtendS.o \

the correct path depends on your setup.
