event.h has bugs

I do not know the package where the header is in.
Testprog:

# include <stdio.h>
# include <event.h>

main(){
printf("All libs ok!");
}

Result:
In file included from libtest.c:2:
/usr/include/event.h:214: error: expected specifier-qualifier-list before ‘u_char’
/usr/include/event.h:292: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token

May be a 32 bit pointer on the 64 bit version? debian lenny 64 bit has the same library and the same bug.
