Don't redefine _GNU_SOURCE in the C++ jsonpull port

mirror of https://github.com/felt/tippecanoe.git synced 2026-10-02 08:25:40 +02:00

The `#define _GNU_SOURCE` carried over from jsonpull.c, where it was
needed to get asprintf() declared. g++ already defines _GNU_SOURCE on the
command line for C++ translation units, so redefining it warns:

    jsonpull/jsonpull.cpp:1: warning: "_GNU_SOURCE" redefined

Guard the define rather than drop it, so platforms whose C++ driver does
not predefine it still get asprintf() declared.
