hello i compiled dash with pcc and found two issues:
src/output.h the outc macro is not standard c:
#define outc(c, file)<->((file)->nextc == (file)->end ? outcslow((c), (file)) :
(*(file)->nextc = (c), (file)->nextc++))
type signature of the operands are int ? void : char*
but the two sides of : should be compatible
either use
... ? outcslow(), 0 : ...
or
... ? outcslow() : ..., (void)0
otherwise a standard compliant compiler won't compile it
the other issue is in the mkbuiltins:
it assumes that the cpp does not produce empty lines with
whitespace only
the following line
< $builtins sed '/^#/d; /^$/d' > $temp
should be
< $builtins sed '/^#/d; /^ *$/d' > $temp
so empty lines with spaces are dropped as well
(allowed by the standard after the preprocessing pass)
(also it would be nice to include a configure script in
the git repo, or don't use autoconf in the first place)
