FS#260 - Patch to let POV-Ray builds with boost >=1.50
Originally resolved in https://bugs.gentoo.org/show_bug.cgi?id=425450.
Attached is a patch with Gentoo-specific code removed.
There are two parts in this issue:
- The newer boost library requires downstream users to explicitly link to the boost system library (-lboost_system).
- The newer boost library replaced TIME_UTC with TIME_UTC_, because glibc added TIME_UTC.
3.7.0-boost-1.50.patch

It appears to me in a review of the code
and configure script, both issues here
were addressed long ago. If I've missed
something, please open a new github
issue for what I missed. Thanks.
The TIME_UTC issue has already been addressed with change #5710 (to be released with RC7) - in a different way though; obviously, just changing TIME_UTC to TIME_UTC_ in POV-Ray would sacrifice compatibility with boost < 1.50, which is not what we want.
Not sure about the -lboost_system. Could this be a Gentoo-specific issue?
I think the `-lboost_system' issue would probably not be a Gentoo-specific issue. The problem lies in that the absence of `-lboost_system' makes the boost thread linking test (in the configure process) fail, and I have not tested whether this absence would cause compile errors.
Testing #5735 [smp], with ubuntu 12.10 & libboost 1.50 (not default)
configure is failing at :
configure:7658: checking whether the boost thread library is usable
configure:7678: g++ -o conftest -pthread -pthread -I/usr/include -L/usr/lib conftest.cpp -lboost_thread-mt -pthread >&5

Adding: LIBS="-lboost_system" to the ./configure line allow to get through.
