Can't compile scsh

[steck@dcs.edinburgh.ac.uk]

Hi,

        I'm trying to compile scsh 0.3 without much luck.  I duly
ran configure first.

        I'm running gcc 2.3.3 on a Sparcstation 20; uname -a returns

> SunOS mealasta.dcs.ed.ac.uk 5.3 Generic_Patch sun4m sparc

which I *think* means Solaris (or does SunOS really mean SunOS).

        The problems begin with compilation of unix.c, where
gcc complains:

> unix.c:135: storage size of `keyboard_action' isn't known
> unix.c:136: storage size of `alarm_action' isn't known

        Hmmm, /usr/include/signal.h includes sys/signal.h,
and struct sigaction is declared there.

        Any clues?
