Thanks, I never knew about that flag. I am using the default 
file. The line that fails is this one:

/software/bin/cc  -DLDC_WITH_PGO -std=c11  
-I/home/abrown/software/ldc/. -I/home/abrown/software/ldc/ddmd 
-I/home/abrown/software/ldc/ddmd/root 
-I/home/abrown/software/ldc/build/ddmd 
-I/home/abrown/software/ldc -isystem 
/Home/abrown/software/llvm/include -isystem 
/home/abrown/software/libs/include     -fPIC -O3 
-DCOMPILER_RT_HAS_ATOMICS=1 -DCOMPILER_RT_HAS_FCNTL_LCK=1 -o 
CMakeFiles/ldc-profile-rt.dir/profile-rt/profile-rt-38/GCDAProfiling.c.o   -c /home/abrown/software/ldc/runtime/profile-rt/profile-rt-38/GCDAProfiling.c

It fails when I call it myself, but succeeds if I drop the 
-std=c11 flag. This I find very puzzling, since I've set in my 
environment variables that CFLAGS='-std=c11' so shouldn't the 
flag also be set when I just call the compiler without options?

Thanks again for all the help.
