Subject: 	* autoload.cc (GetProcessMemoryInfo): Remove.
X-Git-Tag: sid-snapshot-20110601~88
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=34a6eeabfffd0ba2f1db43bae5f7239a49e080bb;p=newlib-cygwin.git

	* autoload.cc (GetProcessMemoryInfo): Remove.
	* resource.cc (fill_rusage): Call NtQueryInformationProcess rather than
	GetProcessMemoryInfo to drop a psapi dependency.
