CMake config (autotools too I think, just did a quick grep) is adding the define -D_XOPEN_SOURCE=500 which (at that version, 500) correctly leaves snprintf() undefined, according to the spec. Given that function is being used in poppler/Catalog.cc, the proper define should be -D_XOPEN_SOURCE=600. Perhaps unrelated to the summary, but also causing compile to fail here, strcasecmp() is being used in 2 places, poppler/GlobalParams.cc and test/perf-test.cc, this is defined on <strings.h> (on both BSD and Linux), which isn't included in the source files (they only have <string.h>, which seems to be enough for Linux).
Can you point to the spec that says that snprintf shall be undefined when -D_XOPEN_SOURCE=500 I added the strings.h include for strcasecmp

About the specs, my apologies I should have included the references while I had them at hand, and "correctly undefined" sounds a bit blunt. Silly of me. To correct myself on the subject, what I found while investigating this is that, since snprintf behavior was redefined between standards [1], the headers only define it (and a few others) when the standard the library supports is in use or requested, which is (usually) SUSv2 or ISO C99 or POSIX98 (not 100% sure on the posix one). While _XOPEN_SOURCE=500 goes back to pre-1998 (speaking of standards) and that (older) implementation of snprintf is not supported on BSD (neither on glibc I think), it's then left undefined (a suggestive way for programs to provide the implementation they want, if I may add). Linux glibc also behaves in a similar way: one of the requisites for defining snprintf in <stdio.h> is "_XOPEN_SOURCE > 500" (coming from <features.h>). But it's then ||or'ed to another define that comes from _BSD_SOURCE (it sets __USE_BSD), which is a bliss for glibc in this case, given that -D_BSD_SOURCE is also defined by poppler here.

Changed to 600, anyway, that option is only set if you use a non standard compile option that you should not be using unless you know what you are doing.
