Error when building

[amcnea]

When trying to build this package on CentOS 6, I received the following error message:

/repos/php-mustache/mustache_data.cpp: In function ‘void mustache_data_from_zval(mustache::Data*, zval*)’:
/repos/php-mustache/mustache_data.cpp:581: error: call of overloaded ‘to_string(long int&)’ is ambiguous

I ended up type casting the offending item as shown in the diff below.

diff --git a/mustache_data.cpp b/mustache_data.cpp
