This was already used in the FAST_CWD check, and could be used in a couple other places. I found the "emulated"/process value returned from the function largely useless, so I did not cache it. It is useless because, as the docs say, it is set to IMAGE_FILE_MACHINE_UNKNOWN (0) if the process is not running under WOW64, but Microsoft also doesn't consider x64-on-ARM64 to be WOW64, so it is set to 0 regardless if the process is ARM64 or x64. You can tell the difference via GetProcessInformation(ProcessMachineTypeInfo), but for the current process even that's overkill: what we really want to know is the IMAGE_FILE_MACHINE_* constant for the Cygwin dll itself, which is conveniently located in memory already, so cache that in wincap also for easy comparisons.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
