Well, cygwin_gethostname is mostly a wrapper around GetComputerName,
IIUC...  Try running the following little script (assumes you have the
"make", "gcc", "gcc-mingw", and "w32api" packages installed):

cat > testGCN.c << EOF
#include <windows.h>
#include <stdio.h>
int main(int ac, char *av[]) {
  DWORD len = 80;
  char name[len];
  if (!GetComputerNameA(name, &len))
    return 1;
  fprintf(stderr, "Got name: '%s'\n", name);
  return 0;
}
EOF
make CC='gcc -mno-cygwin' testGCN
time ./testGCN

If the time it outputs is consistent with what you've been seeing, try
asking on a Windows forum, as this is not a Cygwin problem at all.
Otherwise, you'll need to figure out what else can cause the slowdown.
Does your machine use a DHCP connection?  Does "ipconfig /all" also take a
long time?  In the worst case you may have to build a debuggable version
of cygwin1.dll and spend some time with gdb...
