[B2-devel] vm_alloc.cpp and mach_task_self()

[Nigel P. <ni...@in...>]

	Strange autoconf error. config.log shows:

...
configure:6645: checking for mach_task_self
configure:6682: gcc -o conftest -g -O2   conftest.c  >&5
configure:6685: $? = 0

       #define CONFIGURE_TEST_VM_MAP
       #define TEST_VM_PROT_NONE_READ
       #include "../Unix/vm_alloc.cpp"




	Now, the mach_task_self() prototype is in a strange file
(/usr/include/mach/mach_init.h), so I can understand the barf,
but why did the first test succeed?
