Comment (by Dave-Allured):

 Update.  The type size errors are merely side effects of failing configure
 tests, under the hood.  By comparing the 10.9 log file with other recent
 builder logs, I found an earlier problem:
 {{{
 checking netCDF-4 present... no
 }}}
 This should be "yes".  This comes from `netcdf_meta.h` in the `netcdf`
 dependency.  I confirmed this contains `#define NC_HAS_HDF5 1` which is
 correct.  So this is another under the hood config test that is failing.

 Here is another anomaly, even earlier.
 {{{
 checking for /usr/bin/clang option to enable C11 features... -std=gnu11
 }}}
 This is blank in successful builds for 10.6 and 10.10.  What is causing
 this to be added?  Could this be breaking the configure tests on 10.9
 etc.?
