Installation problem on Cygwin (ABI=32)

[jblazi]

I am trying to install Core, that is a library for exact geometrical=20
compuations. Core needs gmp I should like to work work on *Cygwin*.
When I try to install gmp (I have to input make configure first) I get th=
e=20
error message that ABI=3D32 is not on the ABI list which seemingly only=20
contains 'standard'.
I do not know whether this is a gmp or a Core problem but I suspect that =
I am=20
having this problem with gmp.
Could anybody give me a hint?

TIA,
--=20
