windows build using MSYS about pg_hint_plan

[legrandlegrand]

it seems that postgres files have to be changed like in
https://github.com/bitnine-oss/agens-sql/blob/master/agens_windows/postgresql-9.4.4_win/src/include/optimizer/paths.h

where
extern bool enable_geqo;
extern int geqo_threshold;

has been modified into
extern PGDLLIMPORT bool enable_geqo;
extern PGDLLIMPORT int geqo_threshold;

to support windows builds

this has to be applyed to
src/include/optimizer/paths.h
geqo_threshold
enable_geqo
min_parallel_index_scan_size
min_parallel_table_scan_size

src/include/optimizer/cost.h
max_parallel_workers_per_gather
enable_hashjoin
enable_mergejoin
enable_nestloop
enable_indexonlyscan
enable_tidscan
enable_bitmapscan
enable_indexscan
enable_seqscan
disable_cost

src/include/utils/guc.h
application_name

src/include/miscadmin.h
max_worker_processes

would it be possible to create a patch for pg core
as done here
