The warnings are intel's preprocessor being a bit pickier than gnu's cpp

the errors, though, are indeed odd.
I will eat my sock if strncmp really truly is not on your system; far more likely the strncmp test failed for some unrelated reason.

Look at your src/mpl/config.log.  On my system, the (successful) check for strncmp looks like this:

configure:12723: checking for strncmp
configure:12723: ccache gcc -o conftest -Wall -g -Wno-unused-label -fstack-usage -fPIC -ggdb3   -I /home/robl/work/soft/lustre/include conftest.c  >&5
conftest.c:65:6: warning: conflicting types for built-in function 'strncmp'
 char strncmp ();
      ^
configure:12723: $? = 0
configure:12723: result: yes
configure:12734: checking whether strncmp needs a declaration
configure:12752: ccache gcc -c -Wall -g -Wno-unused-label -fstack-usage -fPIC -ggdb3   -I /home/robl/work/soft/lustre/include  conftest.c >&5
configure:12752: $? = 0
configure:12759: result: no

Does yours look like this?

Hi,

I am getting an error while trying to compile the latest mpich (from the
git repo) with Intel 15.0.1 compiler...excerpt of the error:

Please suggest.
