Peter Foley fa6a5a3a74 Use DnsFree instead of deprecated DnsRecordListFree
The latest version of the mingw headers have been updated to make
DnsRecordListFree an alias of DnsFree when targeting Windows XP or later.
Use DnsFree directly, avoiding the wrapper function.

/home/peter/cross/src/cygwin/winsup/cygwin/libc/minires-os-if.c:289:
undefined reference to `DnsFree'

winsup/cygwin/ChangeLog
autoload.cc: Load DnsFree rather then DnsRecordListFree

Corinna Vinschen 264b5e137e Move definition of wsadata into wsock_init
The problem this patch fixes showed up after updating to gcc-5.3.0.  The
cuplrit is a change in gcc when emitting section attributes.  It only
shows up when building without optimization.  Effect in Cygwin: ws2_32
functions failed to load.

In the original code the definition of "NO_COPY wsadata" was preceeding
an __asm__ block (the definition of the _wsock_init wrapper), while the
definition of "NO_COPY here" immediately follows the same assembler
block.  When gcc-5.3.0 emits assembler code for the wsadata definition,
it emits the .data_cygwin_nocopy section attribute.

Next it emits the assembler output for the __asm_ block, entirely ignoring
its content.  The __asm__ block adds a .text section definition.

Eventually gcc emits assembler code for the here definition.  However,
apparently gcc still "knows" that it just emitted the .data_cygwin_nocopy
section attribute and so doesn't redefine it.  Remember the __asm__?  It
changed the section to .text.

So with gcc-4.9.3 we got:

    .section .data_cygwin_nocopy,"w"
  wsadata:

  __asm__ block:
    .text

    .section .data_cygwin_nocopy,"w"
  here:

With gcc 5.3.0 we now get:

    .section .data_cygwin_nocopy,"w"
  wsadata:

  __asm__ block:
    .text

  here:

So "here" is now in the .text segment which is read-only.  Hilarity ensues.

Corinna Vinschen fcda8810a2 Don't use LoadLibraryEx(..., LOAD_LIBRARY_SEARCH_SYSTEM32). It hangs
Observed running hexchat under X.  For some reason the call to
	LoadLibraryEx(..., LOAD_LIBRARY_SEARCH_SYSTEM32) in dll_load
	hangs when trying to autoload MsgWaitForMultipleObjectsEx in
	select.cc after hexchat forks to run DNS calls.  Dropping the
	call and just using full paths as in 2.3.1 fixes the issue.

	* autoload.cc (dll_load): Drop call to LoadLibraryEx with
	LOAD_LIBRARY_SEARCH_SYSTEM32 flag.
	* wincap.h (wincaps::has_load_lib_search_flags): Remove.
	* wincap.cc (wincaps::has_load_lib_search_flags): Drop handling

Corinna Vinschen b4cf3f454d Revert "autoload.cc: Drop using full paths for system DLLs"
This reverts commit 4b104ce070.

The DLLs always guaranteed to be loaded from the system dir are only
those in the KnownDLLs list.  We're using some DLLs not in that list on
all supported OSes, thus we need to make sure to use full paths.

Corinna Vinschen 859c10beee autload.cc: Avoid clobbering return address in noload on i686
This fixes a long-standing problem when GetProcAddress fails
	to load a function.  The noload code calls SetLastError on
	i686 without saving the edx register.  Starting with Windows 7,
	SetLastError apparently uses $edx and the register is set to
	0x00000000 on return.  So the subsequent `jmp *$edx' in noload
	supposed to return to the caller, actually jumps to address NULL,
	which results in a SEGV.

        * autoload.cc (noload): i686 only: Save and restore $edx when calling
        SetLastError to avoid clobbering return address stating with Windows 7.

tty_min.

to determine if a device is a console.
(_pinfo::_ctty): Use device::parse to generate tty/cons name.
