Could you please try this:

I'm interested in the last (failing) command executed by the last 'make'.
Suppose it is like this:
gcc -std=gnu99 -I. -I./lib -Ilib ... -o lib/stpncpy.o lib/stpncpy.c
Please send the relevant part of the preprocessed output for that command,
i.e., the output of
gcc -E -std=gnu99 -I. -I./lib -Ilib ... lib/stpncpy.c
The failed command was:
===
depbase=`echo lib/stpncpy.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'` ; \
gcc -std=gnu99 -I. -I./lib -Ilib -I./lib -Isrc -I./src -g -O2 -MT
lib/stpncpy.o -MD -MP -MF $depbase.Tpo -c -o lib/stpncpy.o lib/stpncpy.c
===
Attached is the output of:
===
gcc -E -std=gnu99 -I. -I./lib -Ilib -I./lib -Isrc -I./src -g -O2 -MT
lib/stpncpy.o -MD -MP -MF lib/.deps/stpncpy.Tpo lib/stpncpy.c > stnpcpy.E.txt
===
I don't know exactly why, but it seems the definition of "stpncpy" is replaced
From:
===
char *
__stpncpy (char *dest, const char *src, size_t n)
{
char c;
char *s = dest;
===
To:
===
char *
((__builtin_object_size (char *dest, 0) != (size_t) -1) ? __builtin___stpncpy_chk
(char *dest, const char *src, size_t n, __builtin_object_size (char *dest, 2 >
1)) : __inline_stpncpy_chk (char *dest, const char *src, size_t n))
{
char c;
char *s = dest;
===
Which looks like some macro expansion, but I couldn't find the declaration of
this macro.
