SuSE 8.2 QMail 1.03 Installation Issues

The error received when issuing "make setup check" is:

auto-str.c: In function `main':
auto-str.c:17: warning: return type of `main' is not `int'
./load auto-str substdio.a error.a str.a
substdio.a(substdo.o)(.text+0x4e): In function `allwrite':
: undefined reference to `errno'
collect2: ld returned 1 exit status
make: *** [auto-str] Error 1


Fix:
   Edit error.h and add as the very first line:

   #include
