compilation error ggml.c on mac

[jwijffels]

When compiling the R wrapper audio.whisper and looking at the continuous integration messages, I noticed on Mac OS, I see the following error when compiling ggml.c.

clang -mmacosx-version-min=10.13 -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -pthread -DSTRICT_R_HEADERS -std=c++2a -I./dr_libs -I./whisper.cpp -I'/Users/runner/work/_temp/Library/Rcpp/include' -I/usr/local/include  -std=c11 -O3 -D_POSIX_C_SOURCE=199309L -fPIC  -Wall -g -O2  -c whisper.cpp/ggml.c -o whisper.cpp/ggml.o

Can #include <stdio.h> be added?
