Hello,
Using Simons daily-build script I got this failure:
depbase=`echo flock.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
gcc -std=gnu99 -DHAVE_CONFIG_H -DEXEEXT=\"\" -DEXEEXT=\"\" -DNO_XMALLOC
-DEXEEXT=\"\" -I. -I.. -I../intl -D_REENTRANT -g -O2 -MT flock.o -MD -MP -MF
$depbase.Tpo -c -o flock.o flock.c &&\
mv -f $depbase.Tpo $depbase.Po
flock.c:215:2: error: #error "This platform lacks flock function, and Gnulib
doesn't provide a replacement. This is a bug in Gnulib."
make[4]: *** [flock.o] Error 1
This seems to be caused by a bug in flock.c, it checks for HAVE_FLOCK_L_TYPE
but should actually check for HAVE_STRUCT_FLOCK_L_TYPE.
Fixing that it fails thusly:
depbase=`echo flock.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
gcc -std=gnu99 -DHAVE_CONFIG_H -DEXEEXT=\"\" -DEXEEXT=\"\" -DNO_XMALLOC
-DEXEEXT=\"\" -I. -I.. -I../intl -D_REENTRANT -g -O2 -MT flock.o -MD -MP -MF
$depbase.Tpo -c -o flock.o flock.c &&\
mv -f $depbase.Tpo $depbase.Po
flock.c: In function 'flock':
flock.c:186: warning: implicit declaration of function 'memset'

flock.c:202: error: 'errno' undeclared (first use in this function)
flock.c:202: error: (Each undeclared identifier is reported only once

flock.c:208: error: 'EAGAIN' undeclared (first use in this function)
make[2]: *** [flock.o] Error 1
Adding #include <errno.h> takes care of this error.
test-flock then fails like this:
$ ./test-flock
test-flock.c:72: assertion failed, errno = 22
Abort (core dumped)
-tgc
