Are these the messages you are getting?
-------------
Coin6001E Unable to open mps input file ..\Mps\Netlib\e226.mps
Coin0008I  read with -1 errors
Assertion failed: mpsRc==0, file OsiSolverInterfaceTest.cpp, line 1757

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.

If yes, then you are missing the file COIN/Mps/Netlib/e226.mps.

You probably have the file COIN/Mps/Netlib/e226.mps.gz.
The gz file suffix indicates a compressed file format.
In the cygwin environment you should be able to uncompress these files by:
  - cd COIN/Mps/Netlib
  - gzip -d *.gz

In COIN/Examples/Osi/Makefile.basic try changing the line
   CXX := g++
to be
   CXX := g++ -mno-cygwin
I suspect that the link errors are because in the cygwin environment COIN
is now building with the -mno-cygwin option and example makefile you are
using does not have this option specified.
