The parser() function has an option "compilation_mode" which can be set 
to pygccxml.parser.COMPILATION_MODE.ALL_AT_ONCE (default is FILE_BY_FILE):

decls = pygccxml.parser.parse(
    ...<your options here>....,
    compilation_mode = pygccxml.parser.COMPILATION_MODE.ALL_AT_ONCE
)

With this option pyplusplus generates a temporary header (it seems this 
is even done in memory so no temporary file is used, but I haven't 
inspected the sources that closely, so I could be wrong) and invokes 
gccxml only once. So it would relieve you from creating the temporary 
header yourself. The drawback is that this compilation mode totally 
ignores the cache. :(
