On OSF/1 with g++, I'm seeing this error in the test suite:
depbase=`echo test-glob-c++.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`; g++
-DHAVE_CONFIG_H -I. -DGNULIB_STRICT_CHECKING=1 -I. -I. -I.. -I./..
-I../gllib -I./../gllib -mieee -MT test-glob-c++.o -MD -MP -MF $depbase.Tpo
-c -o test-glob-c++.o test-glob-c++.cc && mv -f $depbase.Tpo $depbase.Po
In file included from ../gllib/glob.h:34,
from test-glob-c++.cc:22:
../gllib/sys/stat.h:865: error: invalid conversion from 'int (*)(const char*,
mode_t, ...)' to 'int (*)(const char*, mode_t, dev_t)'
*** Exit 1
The reason is that 'mknod' is declared as
extern int mknod (const char*, mode_t, ...);
whereas gnulib expects
extern int mknod (const char*, mode_t, dev_t);
This fixes it.
