grep-2.5.4-20090203 compilation issues

[Nelson H. F. Beebe]

I've just completed test builds of grep-2.5.4-20090203 in about 25
Unix environments.  While most succeeded and passed their tests, there
are some consistent failures of tests on some systems, notably Sun
Solaris on SPARC and IA-32/EM64T/AMD64.

Compilations report anomalies like these:

        Making all in src
        "grep.c", line 2092: warning: implicit function declaration:
        strcasecmp
        "search.c", line 169: warning: argument #1 is incompatible
        with prototype: prototype: restrict pointer to char :
        "/usr/include/iso/wchar_iso.h", line 300 argument : pointer to
        const char
        "search.c", line 284: void function cannot return value
        "search.c", line 289: void function cannot return value
        "search.c", line 294: void function cannot return value
        c99: acomp failed for search.c

The error also broke builds on DEC OSF/1 Alpha and SGI IRIX MIPS with
native cc.

In compilations on Sun Solaris with three different versions of gcc,
plus Sun cc and Sun c99, the test output looks something like this:

        ...
        PASS: backref.sh
        PASS: file.sh
        Testing:  ../src/grep w. -o -b
          input:  "XwA YwB/ZwC/"
          output: "4:wA/8:wB/12:wC/"
          expect: "1:wA/5:wB/9:wC/"
        FAIL
        ... many more such failures ...
        FAIL
        FAIL: foad1.sh
        SKIP: fmbtest.sh
        PASS: yesno.sh
        =================================
        1 of 13 tests failed
        (1 tests were not run)
        Please report to address@hidden
        =================================

That test also fails on GNU/Linux Alpha, and Mac OS X EM64T (but
passes on Mac OS X PowerPC).
