>Description:
Building sysutils/memtestplus fails on netbsd-5 as follows:

[...]
gcc -Wall -march=i486 -m32 -O1 -fomit-frame-pointer -fno-builtin -ffreestanding 
-fPIC  -fno-stack-protector    -c -o init.o init.c
In file included from init.c:13:
stdin.h:52:27: warning: no newline at end of file
init.c:640:39: error: invalid suffix "b10" on integer constant
init.c:644:42: error: invalid suffix "b10" on integer constant
gmake: *** [init.o] Error 1
*** Error code 2

Stop.
make: stopped in /x/pkgsrc/sysutils/memtestplus
*** Error code 1

Stop.
make: stopped in /x/pkgsrc/sysutils/memtestplus


Looking at the lines reported by the compiler:

   640          if(result != -1) { v->fail_safe |= 0b10; }

   644    if(CONSERVATIVE_SMP) { v->fail_safe |= 0b10; }

I would guess C syntax has evolved "0b" as a prefix to indicate a
base-2 constant?  If so, I would further guess the GCC in netbsd-5 is
too old to know about this.
>How-To-Repeat:
Attempt to build sysutils/memtestplus (5.01) on netbsd-5/i386 (and
probably netbsd-5/amd64).

>Fix:
Patching the code is likely unworkable.  Probably better to require a
later C compiler.  GCC 4.6 is already needed to build "www/firefox" on
netbsd-5.  Perhaps, if it supports the required syntax, it should be a
dependency of sysutils/memtestplus as well.
