/* When compiling for windows, we specify a specific calling convention to
avoid issues where we are being called from a project with a different
default calling convention.  For windows you have 3 define options:

pika_cJSON_HIDE_SYMBOLS - Define this in the case where you don't want to
ever dllexport symbols pika_cJSON_EXPORT_SYMBOLS - Define this on library
build when you want to dllexport symbols (default) pika_cJSON_IMPORT_SYMBOLS
- Define this if you want to dllimport symbol

For *nix builds that support visibility attribute, you can define similar
behavior by

setting default visibility to hidden by adding
-fvisibility=hidden (for gcc)
or
-xldscope=hidden (for sun cc)
to CFLAGS

then using the pika_cJSON_API_VISIBILITY flag to "export" the same symbols
the way pika_cJSON_EXPORT_SYMBOLS does
