Subject: troubles with gnuwin32-egcs-971023...

Sorry if this is a faq, I really did check the archives (well,
most of them, at least) but could not find a useful hint:

gnuwin32-b18 works fine for me, I would like to use some of 
the features of egcs (which I am extensively using on linux
anyway) on nt.

So I downloaded gnuwin32-egcs-971023, set the paths and
started compiling some easy programs.

When I do the linking, I got the following:

C:\test>gcc -g -o iprecv IpRecv.o Application.o -lstdc++
IpRecv.o: In function `main':
/test/IpRecv.cc:122: undefined reference to `htons(unsigned short)'
/test/IpRecv.cc:127: undefined reference to `htonl(unsigned long)'
/test/IpRecv.cc:128: undefined reference to `htons(unsigned short)'
/test/IpRecv.cc:131: undefined reference to `ntohl(unsigned long)'
/test/IpRecv.cc:131: undefined reference to `ntohl(unsigned long)'
/test/IpRecv.cc:145: undefined reference to `htonl(unsigned long)'
gcc: Internal compiler error: program ld got fatal signal 1

so I looked for where the htonl routines are defined and to me
that happens in libcygwin32.a, if I'm not completely wrong.
I figured libcygwin32.a would be included automatically (in
fact, with the cygwin32-b18 I never put that on the link line),
but I figured I'd add it just to make sure:

C:\test>gcc -g -o iprecv IpRecv.o Application.o -lcygwin -lstdc++

well well, it wasn't too smart from me, was it?

Anybody a hint what I am doing wrong?

Thanks a lot and best regards,

Christoph.
