The library was built using the FORTRAN Compiler in the MinGW
installation. The compile options were -O4

>>From gnatmake, the link options were:

-largs -LW:\d-drive\LAPACK -llapack_WindowsXP -lblas_WindowsXP  -LC:
\MinGW\lib -lg2c


The libraries refer to those created by G77 and we note the need for
some modules from g2c.

I have used both Float and Long_Float in instaniations.

Hope this helps.
