Hello everybody,

I'm trying to compile bonmin in cygwin, but I keep getting the same IPOPT
configuration error.
I'm getting the following:

$ ../configure -C

config.status: executing depfiles commands
configure: Creating VPATH links for data files
configure: Configuration of Cbc successful
configure: configuring in Ipopt
configure: running /bin/sh '../../Ipopt/configure'
COIN/coin-Bonmin/build  '-C' --cache-file=../config.cache

configure: error: /bin/sh '../../Ipopt/configure' failed for Ipopt

[1]+  Exit 1                  ../configure -C >config.output

Any ideas? I'm using
cygwin 1.5.21-1
gcc version 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125)
GNU Make 3.80

on a Windows XP (SP2) Dell Latitude D510 laptop.
