Hi All,

I updated Cygwin to 3.4.5-1.x86_64.

$ uname -a
CYGWIN_NT-10.0-19045 DESKTOP-P3E71RB 3.4.5-1.x86_64 2023-01-19 19:09 UTC 
x86_64 Cygwin


However, the same problem occurs.

Cygwn-devel doesn't seem to work.

$ gcc -o selectStdIn selectStdIn.c
selectStdIn.c:9:10: fatal error: sys/select.h: No such file or directory
  #include <sys/select.h>
           ^~~~~~~~~~~~~~
compilation terminated.
