 Hi,

 I got a failing Cgl unit test when Cgl is build under Windows with
 Cygwin, MS Visual C++ 2003, and compile_f2c.
 The problem seem to be that it does not find p0033.mps in the
 Data/Samples directory.
 I searched a bit around where the file opening actually take place, and
 found CoinFileIO.cpp:640.
 There, the string fileName which is given to fopen contains
 {{{
   .\../../Data/Sample/p0033.mps
 }}}
 This probably causes the problem.
 fopen sets errno=2 which means "No such file or directory".

 Someone has an idea why the filename has slash and backslash mixed?

 The strange thing is that even when I change mpsDir in Cgl's unitTest to
 {{{mpsDir = "..\\..\\Data\\Sample\\p0033.mps"}}}
 the test is failing. Now it tries to open
 {{{.\..\..\Data\Sample\p0033.mps}}}
 and still cannot find it.

 The only way I got it working was by calling unitTest in the form
 {{{
 ./unitTest.exe 'echo c:/cygwin/home/svigerske/BuildDir-cl/Data/Sample/'
 }}}
 (where ' is replaced by `)

 This happens for my Windows builds under Cygwin with cl 13.10 or Intel
 10 compilers.

 Best,
 Stefan
