In order to conform final SRFI-22,
Gauche release 0.5.1 changes the way
main is called.
Unfortunately, this makes the Scheme scripts that is written for older
Gauche no longer work.
I decided to take this change now, in the early stage of Gauche,
rather than keeping incomatibility to the standard (srfi).
The incompatible changes are these two points.
mainnow includes the script name itself as the first element. In older version, only the arguments after the script file name are passed.
mainreturns non-integral value,
goshexits with code 70. In older version,
goshexits with code 0 in such case.
