The unconditional use of -D_FORTIFY_SOURCE=2 can lead to compile failures on older systems. It is also unclear why this should be unconditionally turned on. I would recommend removing it from Makefile.in, if you want it you can always specify it via CFLAGS/CPPFLAGS.

Example output of a failed built on an Itanium machine:

checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables... 
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking for strlcpy... no
checking for strlcat... no
checking for strndup... yes
checking whether to enable strict mode... (cached) no
checking how to run the C preprocessor... cpp
checking for gcc... (cached) gcc
checking whether we are using the GNU C compiler... (cached) yes
checking whether gcc accepts -g... (cached) yes
checking for gcc option to accept ISO C89... (cached) none needed
checking for a BSD-compatible install... /usr/bin/install -c
checking whether ln -s works... yes

The unconditional use of -D_FORTIFY_SOURCE=2 can lead to compile failures on older systems. It is also unclear why this should be unconditionally turned on. I would recommend removing it from Makefile.in, if you want it you can always specify it via CFLAGS/CPPFLAGS.

-D_FORTIFY_SOURCE=2 is added for security reasons. On some libc's it uses substitute functions which are more secure. It shouldn't have this sort of effect.

I know what you are trying to achieve. Still, underscore-capital letter names are reserved. Portable code must either not use them, or use autoconf tests to determine if the compiler (and libc in this case) supports them.
