A user with GCC 5.2 and GLibc 2.22 reported that patch isn't buildable.


===> Building for nbpatch-20100124
gcc -O2  -Werror  -DHAVE_NBCOMPAT_H=1
- -I/home/jack/netbsd-pkgsrc/pkgsrc/devel/nbpatch/work/libnbcompat -c
patch.c
patch.c: In function main:
patch.c:178:6: error: implicit declaration of function asprintf
[-Werror=implicit-function-declaration]
  if (asprintf(&TMPOUTNAME, "%.*s/patchoXXXXXXXXXX", i, tmpdir) == -1)
      ^
cc1: all warnings being treated as errors
*** Error code 1

We went for addition of AC_GNU_SOURCE to
pkgtools/libnbcompat/files/configure.ac and `autoreconf -fiv' over
pkgtools/libnbcompat/files

It solved the issues.
