Description of Problem:

Hello there,

I just tried to compile package pxe-0.1-33 from Redhat 8.0.

Here are some of the compiler messages.

discover.c:168: warning: `n' might be used uninitialized in this function
discover.c:168: warning: `n' might be used uninitialized in this function
discover.c:242: too few arguments to function `unicast_discover'
discover.c:286: too few arguments to function `multicast_discover'
discover.c:299: too few arguments to function `broadcast_discover'
discover.c:310: too few arguments to function `unicast_discover'
misc.c:5: conflicting types for `cksum'
misc.h:61: previous declaration of `cksum'
apstring.cc:437: warning: returning reference to temporary
cproxreg.cc:93: warning: `char*pImageName' might be used uninitialized in this
pxeparser.cc:91: warning: `BYTE*pucDhcpPacket' might be used uninitialized in
pxeparser.cc:391: warning: `int nCredLen' might be used uninitialized in this

It seems that Bruce's c compiler (bcc) doesn't do as much checking as
the GNU C compiler. Here is an untested patch which seems to shut up
the compiler.
