I have a 64bit Vista machine.

Please help me fix these two errors so I can compile, they seem to be relat=
ed to winsock in some way

PLEASE HELP

I'm trying to compile a C program and here is what I'm getting:

make: *** [ibsp.exe] Error 1

Alright I was able get Cygwin working and GCC and the makefile program inst=
alled and the path variable set with
export PATH=3D$PATH:/bin:/usr/bin

for command like ls and such

and

export PATH=3D$PATH:/lib

for gcc

then I made a directory in /usr/ibs
I put all of the ibs stuff there to be compiled.

I did:

make -f Makefile

to run
 the make file.

It gave me several warnings and two errors.=20

The two errors are:

net.c:112: error: 'struct _types_fd_set' has no member named 'fd_count'
net.c:113: error: 'struct _types_fd_set' has no member named 'fd_array'

I have done some research and I think it is due to the winsock stuff in the=
 win32 api not compiling properly for some reason. I'm thinking there is so=
me other version of the winsock.h and winsock2.h I need other then the ones=
 that came by default in C:\cygwin\usr\include\w32api . Soo this is what I'=
m trying to figure out.

Can someone please help =3D)? Well that's where I got so far in compiling I=
'll continue to research for a fix for this.

I wanted add about the:

net.c:112: error: 'struct _types_fd_set' has no member named 'fd_count'
net.c:113: error: 'struct _types_fd_set' has no member named 'fd_array'

It looks like net.c is trying to use a structure type of a structure
 defined in winsock.h. In this definition fd_count and fd_array are indeed =
members. For some reason net.c can't see its members...I don't think the in=
cludes have to be changed because this code was compiling and running just =
fine on the previous developers machine. I'm thinking that the winsocck API=
 installed default from cygwin on my machine is different and needs patched=
 or changed in some way
