[Rd] #include_next <stdio.h> not found

[Roy Mendelssohn - NOAA Federal]

Hi Roger:

This came up in the r-sig-mac list.  Try removing the CPPFLAGS.   Updates to Xcode appear to erase the headers where you are pointing to.  The CRAN flags that Simon uses  point elsewhere. Look at the r-sig-mac under topic "Xcode 10.3 and header flles".

HTH,

-Roy
