[Coin-bcpdiscuss] BUG: Bcp-1.1.0 on cygwin

[Ted Ralphs]

I've seen this error before and it most likely has something to do with 
the -mno-cygwin flag. However, before you do anything else, make sure 
you are using the correction version of make. On CYGWIN, the default 
version of make installed by the setup program doesn't work. See:

https://projects.coin-or.org/BuildTools/wiki/current-issues

What arguments did you give to configure? If you are using 
--enable-doscompile, I would also try building without that flag and see 
if that fixes the error. If you did not specify --enable-doscompile and 
got the -mno-cygwin flag anyway, then there is probably something 
missing from your CYGWIN installation. In any case, please post your 
config.log, so we can try to track down the problem.

Cheers,

Ted
