Hi Everyone,
I'm trying to build Emacs on Cygwin. I use the platform as a test bed
because of Newlib. Emacs is failing with:
gcc -DHAVE_CONFIG_H -I. -I../lib -I../src -I../src
-I/usr/local/include -DNDEBUG -pthread -D_XOPEN_SOURCE=600 -m64 -MT
close-stream.o -MD -MP -MF .deps/close-stream.Tpo -c -o close-stream.o
close-stream.c
In file included from /usr/include/sys/signal.h:22:0,
from /usr/include/signal.h:6,
from ./signal.h:52,

from binary-io.c:3:
/usr/include/cygwin/signal.h:175:3: error: unknown type name ‘pthread_attr_t’
pthread_attr_t *sigev_notify_attributes; /* notification attributes */
^~~~~~~~~~~~~~
Examining /usr/include/cygwin/signal.h around 175, I see:
typedef struct sigevent
{
sigval_t sigev_value; /* signal value */
int sigev_signo; /* signal number */
int sigev_notify; /* notification type */
void (*sigev_notify_function) (sigval_t); /* notification function */
pthread_attr_t *sigev_notify_attributes; /* notification attributes */
} sigevent_t;
But I don't see an include for the pthread gear in the signal.h header file.
I found one past message that's similar
(https://cygwin.com/ml/cygwin/2016-06/msg00458.html), but its reported
as an upstream bug.
