Don't unnecessarily redefine 'socklen_t' type in MinGW builds.
The original configure-time tests in gdb/ and gdbserver/ failed to
detect that 'socklen_t' is defined in MinGW headers because the test
program included only sys/socket.h, which is absent in MinGW system
headers. However on MS-Windows this data type is declared in another
header, ws2tcpip.h. The modified test programs try using ws2tcpip.h
if sys/socket.h is unavailable.
Thanks to Joel Brobecker who helped me regenerate the configure
scripts and the config.in files.
gdb/ChangeLog:
2020-07-26 Eli Zaretskii <eliz@gnu.org>
* configure.ac (AC_CHECK_HEADERS): Check for sys/socket.h and
ws2tcpip.h. When checking whether socklen_t type is defined, use
ws2tcpip.h if it is available and sys/socket.h isn't.
* configure: Regenerate.
* config.in: Regenerate.
gdbserver/ChangeLog:
2020-07-26 Eli Zaretskii <eliz@gnu.org>
* configure.ac (AC_CHECK_HEADERS): Add ws2tcpip.h.
When checking whether socklen_t type is defined, use ws2tcpip.h if
it is available and sys/socket.h isn't.
* configure: Regenerate.
* config.in: Regenerate.
