With DragonFlyBSD 3.8 / i386 I see these problems in a gnulib testdir:
1) A warning
freadahead.c: In function 'freadahead':
freadahead.c:39:3: warning: implicit declaration of function '__sreadahead'
[-Wimplicit-function-declaration]
2) A failure
FAIL: test-get-rusage-data
(assertion failed at test-get-rusage-data:60)
3) A failure
FAIL: test-localeconv
(assertion failed at test-localeconv.c:41)
4)
FAIL: test-select
Invalid fd test... failed
Fixed through the attached changesets.
NOT FIXED:
1)
FAIL: test-dup2
(assertion failed at test-dup2.c:163)
FAIL: test-getdtablesize
(assertion failed in test-getdtablesize.c:32)
2) A warning
test-float.c: In function 'test_long_double':
test-float.c:315:5: warning: floating constant exceeds range of 'long double'
[-Woverflow]
and failures
FAIL: test-float
(assertion failed at test-float.c:318)
FAIL: test-fmal2
(assertion failed at test-fma2.h:538)
3) A failure
FAIL: test-localename
(assertion failed at test-localename.c:183)
LC_CTYPE inheritance appears to be broken.
