Hello!

According to Gary Narayanan USG:

1. The compiler (I think is gcc 2.7.2.1 compiles this and not /usr/bin/cc) could not compile the file "gpc-decl.c" . The error was in line 2962

    TREE_CODE (TREE_VALUE (tail)) = code; 
   
   The compile said it was not an l-value.
   
   

I worked around by eliminating the conditional, and typing

    return NULL_TREE;

for both cases. Will this break the compiler functionality?

Yes.

It must have been `/usr/bin/cc' since gcc-2.7.2.1 is known to accept this. The problem comes from the `TREE_CODE' macro being a type cast which is not accepted by all C compilers as an lvalue.

To work around, replace the line by

(TREE_VALUE (tail))->common.code = code;

2. The file "gpc-module.c" has several '#define' statements and not starting at first character of the line. The link editor failed because of this, eg

   ld: unreolved STORE_SPECIAL

Fixed. Thanks.

3. The rts/Makefile generated needed some editiong, ie adding a "../" for the gcc path name.

Here I am not sure. Maybe this comes from some VPath problem? Anyway, more recent versions of GPC have an automatically generated `rts/Makefile' which hopefully does not cause this problem.
