[sdcc-devel] Some improvements to sdcc 2.3.0 (I hope)

[Vladimir <vt...@in...>]

Hi.

I have not tested the attached patch in all the platforms, just
Linux and partially OpenBSD.  If release it to the public domain.

What I wanted to improve was:
* Compilation and installation on OpenBSD (now compiles and installs at=20
  least in OpenBSD 3.1)
* Better support for paths that include . (e.g ../../mysource.c) in
  mcs51 and sdcc
* Allowing several declarations of the same variable, but just one defini=
tion

For example withouth the patch the following correct (I think) code canno=
t
be compiled:
---

int x;
int x;

int main() {
        return 0;
}
---

With the patch it compiles and installs good in OpenBSD 3.1=20
with the following patch to sed of OpenBSD 3.1 (autoconf generates
some 'r' instructions for sed but without filename):
RCS file: /cvs/src/usr.bin/sed/compile.c,v
retrieving revision 1.11
diff -r1.11 compile.c
278,281c278
<                       if (*p =3D=3D '\0')
<                               err(COMPILE, "filename expected");
<                       else
<                               cmd->t =3D duptoeol(p, "read command");
---
>                       cmd->t =3D duptoeol(p, "read command");

I already sent that patch to the OpenBSD developers, don't know if it
will be accepted.

Best regards
