By the way, the default compilation for python modules is with
the flag -Wstrict-prototypes.
It used to generate a number of warnings, and after I reported
it on the r-devel list, it was solved (for R-2.7).
(well mostly, there is a last warning:
include/R_ext/Rdynload.h:26: warning: function declaration isn't a prototype
)
The following part in setup.py (trunk, that is version 1.x) can eventually
be changed:
if DEBUG:
# to avoid strict prototypes errors from R includes
get_config_vars()['OPT'] = '-g -Wall'
else:
# to avoid strict prototypes errors from R includes
get_config_vars()['OPT'] = '-DNDEBUG -g -O3 -Wall'
