This is a hard-coded limit, so there is no magical compiler option to
raise it. There can be no more than 248 nonconstant constructors in a
variant type.
However, if your constructors are constant (they have no parameter),
then this is a now corrected bug. See PR#117 in the caml bug tracking
system.
With the corrected version of the compiler, you may use 2^31 constant
constructors independently of the 248 nonconstant ones.
As a temporary workaround you may use polymorphic variants: it should
be possible to use tens of thousands of both constant and nonconstant
constructors in the same type.
