Hi all,

I have found that GotoBlas had a mailing list and there I had same 
support from guys using the library. In fact the main maintainer does 
not answer to any mails since months... One guy had forked the GotoBlas 
library to OpenBLAS (https://github.com/xianyi/OpenBLAS) and he found 
fixes in order to compile the library using mingw (mostly in c_check and 
f_check files).

If someone has the same issues he should enjoy the OpenBLAS repository!
