Mpc contains the following in src/mpc.h (since mpc-0.6 in 2009):
/* Define MPC version number */
#define MPC_VERSION_STRING "1.0.2"

Excellent! You may wish to have a look at the bug report to coordinate your
efforts. A paragraph I just posted which is relevant to the discussion
(although as I am speaking about mpc, maybe on the wrong list here):

"Even if you are not using always the latest version of the multiprecision libraries, the ftp server and download script should nevertheless be updated from time to time. Moreover, at least for mpc (I cannot speak for the others, but I think there it also holds) you should always use the latest bug fix release in a release series. Since the 1.0.0 version, we maintain a separate branch for the 1.0 series; so 1.0.2 is strictly a bug fix release, and new functionality will go into the 1.1 release series. After the 1.1 release, we will continue to maintain the 1.0 branch for a while. Details have not been decided yet, but I think that in any case, once the 1.2 release is out, the 1.0 branch will not be maintained any longer. At this point in time, you should definitely switch to a newer release in the download script.

Right now, the 0.8 and 0.9 versions are unmaintained; we started a more conservative policy of releasing and backporting bug fixes in 2012 with 1.0 (as indicated by the version number...)."

This goes against your wishes of updating rather infrequently...
