I came back to this and just tried it out... for me this is not a solution. I 
do get exactly the same warnings as before.

I already removed '-pedantic' from my CFLAGS, but still get lots of these:

In file included from xsize.c:3:0:
xsize.h:63:1: warning: no previous prototype for 'xsum' [-Wmissing-prototypes]
 xsum (size_t size1, size_t size2)
 ^
xsize.h:74:1: warning: no previous prototype for 'xsum3' [-Wmissing-
prototypes]
 xsum3 (size_t size1, size_t size2, size_t size3)
 ^
xsize.h:84:1: warning: no previous prototype for 'xsum4' [-Wmissing-
prototypes]
 xsum4 (size_t size1, size_t size2, size_t size3, size_t size4)
 ^
xsize.h:94:1: warning: no previous prototype for 'xmax' [-Wmissing-prototypes]
 xmax (size_t size1, size_t size2)


Looking at the header files (e.g. xsize.h), it does not make sense to have 
prototypes here... gnulib should have AM_CPPFLAGS += -Wno-missing-prototypes.

Not sure, if it is worth asking.
