2014-01-02	disable sbrk for all values of increment except 0	Rich Felker	1	-3/+3
	use of sbrk is never safe; it conflicts with malloc, and malloc may be used internally by the implementation basically anywhere. prior to this change, applications attempting to use sbrk to do their own heap management simply caused untrackable memory corruption; now, they will fail with ENOMEM allowing the errors to be fixed. sbrk(0) is still permitted as a way to get the current brk; some misguided applications use this as a measurement of their memory usage or for other related purposes, and such usage is harmless. eventually sbrk may be re-added if/when malloc is changed to avoid using the brk by using mmap for all allocations.
2011-09-26	cleanup various minor issues reported by nsz	Rich Felker	1	-2/+2
	the changes to syscall_ret are mostly no-ops in the generated code, just cleanup of type issues and removal of some implementation-defined behavior. the one exception is the change in the comparison value, which is fixed so that 0xf...f000 (which in principle could be a valid return value for mmap, although probably never in reality) is not treated as an error return.
