[Help-gsl] GSL and VB6

I'm trying to use GSL's dlls with Visual Basic 6.0. I'm declaring some test 
functions like this

Public Declare Function gsl_acosh Lib "libgsl.dll" (ByVal x As Double)

but I get the error "Bad DLL calling convention" ( error 49 ) when I call it 
like, for example

Dim a As Double
a = gsl_acosh(0.2)

Does anyone knows what is wrong here? The debug gives the error on the 
"a=gsl_...". It seems to find the function, but it doesn't work.

Please answer as soon as possible.

Kind regards,
