pecl install mongodb fails on Cygwin (64-bit)

Description

Trying to install the mongodb extension through Cygwin (64-bit, not tested 32-bit) using pecl install mongodb and it fails with the following errors:

src/libmongoc/src/mongoc/.libs/mongoc-client.o: In function `_mongoc_get_rr_search':
/tmp/mongodb-1.4.3/src/libmongoc/src/mongoc/mongoc-client.c:413: undefined reference to `__ns_initparse'
/tmp/mongodb-1.4.3/src/libmongoc/src/mongoc/mongoc-client.c:413:(.text+0xeb): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `__ns_initparse'
/tmp/mongodb-1.4.3/src/libmongoc/src/mongoc/mongoc-client.c:430: undefined reference to `__ns_parserr'

collect2: error: ld returned 1 exit status
make: *** [Makefile:619: mongodb.la] Error 1

Environment

PHP 7.1.16 from Cygwin's setup 'package manager'.

Expected and Actual Behavior

Expected it to compile, but it doesn't.

I can get make to 'succeed' by including -l/usr/lib/resolv.a (pecl download mongodb etc and then manually edit the Makefile), but it outputs only two files and no dll:

/tmp/mongodb-1.4.3 [1] $ ls modules/
mongodb.a  mongodb.la

The mongodb.a doesn't appear to be a dll format either, so it's not just a name thing.

Hi!

We do not support Cygwin installs of PHP, as it is not part of PHP's standard mode of distribution for Windows.

Binaries for each release are automatically built, and end up on the PECL package page where you can download them.

If you want to build the binaries yourself, please refer to the build instructions on our Contributing page.

cheers,
Derick
