Building ttfautohint (http://repo.or.cz/ttfautohint.git/) on OS X
10.10 (XCode 6.4) fails. The data below is taken from a travis build
(https://travis-ci.org/source-foundry/ttfautohint-build/jobs/269031319#L3401).
Here's the list of the gnulib modules I use in ttfautohint:
dirname
fcntl-h
getopt-gnu
git-version-gen
isatty
memmem-simple
progname
stdarg
stdbool
stdint
strerror_r-posix
strndup
strtok_r
strtoull
vasprintf

[there are obviously two output streams intermingled in the log file;
I haven't cleaned up the messages]
Note that ttfautohint can be compiled fine with OS X 10.11 and newer;
it also succeeds on OS X 10.5.8 (which still uses gcc by default).
