I'll look into these one at a time and see how many I can fix.

Comment:
Patch submitted for the bltinmodule.c warning.

The errors.c warnings are because isdigit() & friends expect
an int, and the code is using *f, which is a char.  isdigit() is a macro on Solaris.  Presumably the fix is to use (int)*f on those lines.   Same cause for the ones in stropmodule.c and intobject.c, I think.

The warnings in socketmodule.c, and presumably the ones
in signalmodule.c, intrcheck.c, and pythonrun.c too, seem to be because of Solaris's SIG_IGN.  I suspect GCC is getting confused by it.
