Subject: No need to use mpicc to compile the plot_image examples.  Use gcc instead.
X-Git-Url: http://git.tremily.us/?p=parallel_computing.git;a=commitdiff_plain;h=68c095834b5dbd9813f95829777264946af738f9

No need to use mpicc to compile the plot_image examples.  Use gcc instead.

This requires linking libm explicitly to define `sin` and `cos`.
