Intel C Compiler fails to compile test/ccalltest.c due to the presence of complex integer literals

[psanan]

During a (re)build, I encountered a "1909: complex integral types are not supported" error when using the intel C compiler (icc 14.0.2 20140120 ).

The build proceeds normally if the following changes are made (from b299179)

Fixed in a more recent version of the compiler?

[psanan]

I seem to have version 14.0.2 which is later than the purported fix in that link (10.1.031).

I have also left a note on the commit which closes this issue, but one instance of 2i remains in ccalltest.c, which I needed to convert to (2.0)*I to build with the intel compiler mentioned above.

I think 03da3a3 should fix the issue. @psanan Can you confirm?
