title: Compiling through macOS Terminal, fatal error: stdio.h: No such file or directory
body: <p>So was trying to compile a c file (via a makefile) and got the "fatal error: stdio.h: No such file or directory" . This compiles on just fine via cygwin and a remote linux box just not my mac (so the files are okay). </p>
  
  <p>I have installed the mac command line tools as mentioned in <a href="https://stackoverflow.com/questions/19580758/gcc-fatal-error-stdio-h-no-such-file-or-directory">this</a> question. When I do gcc --version I am getting 5.3 but if i do brew info gcc i get 8.2.  When I do a find through terminal I can the file, so not sure what is up. </p>
