variable.
* dlfcn.cc (get_full_path_of_dll): Search /usr/bin (for windows compatibility)
and /usr/lib (for UNIX compatibility) when looking for shared libraries.
* environ.cc (conv_envvars): Put back LD_LIBRARY_PATH since it is used by
get_full_path_of_dll().
* errno.cc (errmap): Map MOD_NOT_FOUND to ENOENT.
* cygmagic: Remove debugging cruft.

collision with large data areas.
* fhandler_console.cc (fhandler_console::get_tty_stuff): Accommodate changes to
open_shared arguments.
* fhandler_tape.cc (mtinfo_init): Ditto.
* pinfo.cc (pinfo::init): Use open_shared rather than win32 mmap calls.
* shared.cc (user_shared_initialize): Ditto.
(memory_init): Ditto.
(open_shared): Change to allow use a smore general mmap handler.
* shared_info.h (shared_locations): Add SH_JUSTCREATE, SH_JUSTOPEN.
(open_shared): Change declaration to match new usage.
* autoload.cc (LoadDLLfuncEx2): Define in terms of LoadDLLfuncEx3.
(LoadDLLfuncEx3): New macro.

(CURR_CHILD_INFO_MAGIC): Update.
(child_info::magic): Make 'long'.
* cygheap.h: Export _cygheap_start.
* cygheap.cc: Don't declare _cygheap_start.
* cygmagic: Use cksum to produce checksums. Append 'U' to end of checksum.
* dcrt0.cc (initial_env): Calculate sleep ms before reusing buffer.
(_dll_crt0): Detect cygheap mismatch as indicative of different cygwin version.
Set child_proc_info to NULL when _PROC_WHOOPS.
(multiple_cygwin_problem): If child_info specific problem, then set
child_proc_info type to _PROC_WHOOPS.

* dcrt0.cc (_dll_crt0): Check for changes in child_info size.
(multiple_cygwin_problem): Avoid "proc" errors when testing. Just assume new
cygwin proc.
* shared_info.h (mount_info): Add 'cb' element for sanity checks.
(shared_info): Ditto.
* child_info.h (child_info): Add fhandler_union_size element for sanity
checking.
* shared.cc (open_shared): Detect shared region size mismatch between parent
and child.
(shared_info::initialize): Detect shared region size mismatch with expectation.
(memory_Init): Ditto.
* sigproc.cc (init_child_info): Correctly set cb in passed structure.
* shared.cc (open_shared):

Force dependencies for files which depend on autogenerated headers to ensure
that they are always built.
* child_info.h (child_info): Add new fields to accommodate new magic number
header stuff.
* dcrt0.cc: Rely on "child_info_magic.h" to ensure that correct child_info
magic numbers are used.
(dll_crt0_1): Temporarily remove _cygwin_testing_magic test.
(_dll_crt0): Do more testing on magic numbers from fork_info structure. Call
"multiple_cygwin_problem" where appropriate.
(multiple_cygwin_problem): Rename from multiple_cygwin_die. Issue a warning or
die, as appropriate based on cygwin version/magic number mismatch.
* pinfo.cc (pinfo::exit): Don't attempt to dereference `this' if it doesn't
exist. This can happen when a fatal error occurs early in process
initialization.
* shared.cc: Rely on "shared_info_magic.h" to accommodate that new magic number
header stuff.
(shared_info::initialize): Use new magic number stuff, for shared region.
(memory_init): Ditto, for mount table.
* shared_info.h: Accomodate new magic number stuff for shared region and mount
table.
* sigproc.cc: Rely on "child_info_magic.h" to accommodate new magic number
header stuff.
(init_child_info): Initialize new fields in child_info) to accomodate magic
numbers.
* winsup.h: Rename multiple_cygwin_die to multiple_cygwin_problem.
* include/cygwin/version.h: Define macros for manipulating version magic.
* cygmagic: New shell script for generating magic numbers.
