grep-2.6.3 build feedback

[Nelson H. F. Beebe]

I now have grep-2.6.3 successfully built, validated, and installed in
our test lab (25+ flavors of Unix).  The only failures are on rather
old systems, or in small subset of tests where one wonders whether
grep is in error, or the tests themselves are possibly faulty:

        DEC Alpha OSF/1 4.0:
                FAIL: test-exclude2.sh
                FAIL: test-exclude5.sh
                FAIL: test-unsetenv

        MirBSD 10 IA-32:
                FAIL: test-mbrtowc3.sh
                FAIL: test-mbsrtowcs3.sh
                FAIL: test-wcrtomb.sh

        NetBSD 5.0.2 IA-32:
                FAIL: test-nl_langinfo.sh

        OpenBSD 4.7 IA-32:
                FAIL: test-unsetenv

        Open Solaris 11 AMD64:
                FAIL: test-exclude2.sh
                FAIL: test-exclude5.sh
                FAIL: test-quotearg.sh

        Solaris 10 AMD64:
                FAIL: test-exclude2.sh
                FAIL: test-exclude5.sh

        Solaris 10 IA-32:
                FAIL: test-exclude2.sh
                FAIL: test-exclude5.sh

        Solaris 10 SPARC:
                FAIL: test-exclude2.sh
                FAIL: test-exclude5.sh

On OSF/1 Alpha, compilation failed like this:

          CC       kwset.o
        kwset.c: In function `kwsalloc':
        kwset.c:101: error: `malloc' undeclared (first use in this function)
        kwset.c:101: error: (Each undeclared identifier is reported only once
        kwset.c:101: error: for each function it appears in.)

I trapped the preprocessor output, and found that the line

        obstack_init(&kwset->obstack);

expands to

        _obstack_begin ((&kwset->obstack), 0, 0,
                       (void *(*) (long)) malloc,
                       (void (*) (void *)) free);

I replaced the line kwset.c:45

        # define malloc(s) xmalloc(s)

by

        # define malloc xmalloc

because malloc appears without an argument list in the definition of
_obstack_begin() in lib/obstack.h from the setting

        #define obstack_chunk_alloc malloc

in kwset.c.

Compilation then completed successfully, and all tests passed, EXCEPT
for the three tests listed above.

On SGI IRIX 6.5, compilation fails because of type confusion from
gcc-3.4.6's <stdint.h>:

        CC       uniwidth/width.o
        In file included from ./stdint.h:59,
                         from ./unitypes.h:23,
                         from ./uniwidth.h:23,
                         from uniwidth/width.c:23:
        /usr/local/ashare/gcc-3.4.6/include/stdint.h:10: error: syntax error 
before "int64_t"
        /usr/local/ashare/gcc-3.4.6/include/stdint.h:15: error: syntax error 
before "uint64_t"
        /usr/local/ashare/gcc-3.4.6/include/stdint.h:20: error: syntax error 
before "int_fast64_t"
        /usr/local/ashare/gcc-3.4.6/include/stdint.h:25: error: syntax error 
before "uint_fast64_t"
        /usr/local/ashare/gcc-3.4.6/include/stdint.h:27: error: syntax error 
before "uintmax_t"
        /usr/local/ashare/gcc-3.4.6/include/stdint.h:28: error: syntax error 
before "intmax_t"

The last version of GNU grep to build successfully on that system is
2.5.4, so we may just have to consider it unsupported in current grep
releases.

On Solaris 7 SPARC (another rather old system), compilation fails like
this:

        CC       isdir.o
        In file included from sys/stat.h:48,
        isdir.c:23:
        sys/stat.h:861: warning: `struct stat' declared inside parameter list
        sys/stat.h:861: warning: its scope is only this definition or 
declaration, which is probably not what you want.
        isdir.c: In function `isdir':
        isdir.c:30: storage size of `stats' isn't known

The last successful grep build on that system was 2.5.1 (November
2004), so it too may be left behind.
