Between your suggested change to _findcc() and Chris Marshall's suggestion, I've arrived at: 
sub _findcc {
    my @flags = @Config{qw(ccflags ldflags)};
    @flags = grep { length } map { quotewords('\s+', 1,$_) } @flags;

That works pretty well. There's now just the one failing test in the Devel::CheckLib test suite: 
t/multi-word-compiler.........Subroutine STORE redefined at C:/_32/ap1
+005/lib/Config_heavy.pl line 1177.
Set up gcc environment - 3.4.5 (mingw-vista special r3)
%Config::Config is read-only
# Looks like your test died before it could output anything.
t/multi-word-compiler.........dubious
        Test returned status 255 (wstat 65280, 0xff00)
DIED. FAILED test 1
        Failed 1/1 tests, 0.00% okay

Looks like STORE gets redefined to a form that we don't want. I think the error is in response to the following line in t/multi-word-compiler.t: 
$Config{cc} = "$^X $Config{cc}";

Needless to say, 'perl -Mblib t/multi-word-compiler.t' passes the test :-)))) 

C:\_32\comp\Devel-CheckLib-0.91>perl -Mblib t/multi-word-compiler.t
1..1
Set up gcc environment - 3.4.5 (mingw-vista special r3)
ok 1 - Good multi-word compiler is OK
