with -ffreestanding

LC_ENTER "foo.c"
LC_RENAME "<command-line>"
LC_ENTER "foo.h"
LC_LEAVE 0x0
LC_RENAME "foo.c"
<- correct output printed here
LC_LEAVE 0x0

so std-predef.h is not included.


I tried with -include foo.h and a breakpoint in push_command_line_include...  I
just stepped through from that breakpoint and saw cpp_push_default_include
being called for both stdc-predef.h and foo.h.  That also gives the correct
output.

# gcc-4.9 -include foo.h foo.c
foo.c: In function ‘main’:
foo.c:1:21: error: expected expression before ‘}’ token
 int main() { return }
