Right, that settles it; your installation is just broken somehow.
admin@ubik /usr/include
$ grep "pthread_attr_t" sys/*.h
sys/signal.h: pthread_attr_t *sigev_notify_attributes; /* Notification
Attributes */
sys/types.h:} pthread_attr_t;
admin@ubik /usr/include

Something must have gone wrong during the installation. You could perhaps
fix it by rerunning setup.exe and seeing if it finishes off any part-installed
jobs. Just for curiousity, what does the copy of types.h that you have look
like? Is it possibly truncated? Did your disk perhaps fill up (maybe only
transiently) during the install?

No, that is completely incorrect in every way. The "problem" is the correct
behaviour of the C compiler on any platform when fed damaged header files, and
Cygwin does not use MinGW tools, although it does supply a MinGW
cross-compiler *as well as* the native one.

All the mirror sites listed on the cygwin.com page are regularly verified
for correctness by a script. Reinstalling from scratch is probably a little
drastic, why not just reinstall on top? On the setup.exe package selector
screen, bring up the Categories tree view, and click on the topmost category
until it cycles to "Reinstall". But first just try running setup.exe straight
through and seeing if it finishes off anything that didn't complete previously.
