[Coin-bcpdiscuss] BCP examples won't build on CYGWIN environment.

[Gualtiero Tramezzi]

Hello, I've built and installed BCP libraries on a CYGWIN environment but I 
cannot
build BCP examples. For example MaxCut gives me this error:

$ make

g++ -O3 -fomit-frame-pointer -mno-cygwin -pipe -DNDEBUG -pedantic-errors 
-Wimpli

cit -Wparentheses -Wreturn-type -Wcast-qual -Wall -Wpointer-arith 
-Wwrite-string

s -Wconversion   `for i in include   /usr/include; do cygpath -w $i | sed -e 
's/

^/-I/'; done` -c -o CG/MC_cutgen.o `test -f 'CG/MC_cutgen.cpp' || echo 
'/'`CG/MC
