I've now figured out. It would be also better if configure.ac was self contained. If I modify it and run autoconf I get: configure.ac:366: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE call detected in body autoconf/lang.m4:198: AC_LANG_CONFTEST is expanded from... autoconf/general.m4:2599: _AC_COMPILE_IFELSE is expanded from... autoconf/general.m4:2609: AC_COMPILE_IFELSE is expanded from... ../../lib/m4sugar/m4sh.m4:610: AS_IF is expanded from... autoconf/general.m4:2047: AC_CACHE_VAL is expanded from... autoconf/general.m4:2060: AC_CACHE_CHECK is expanded from... configure.ac:366: the top level if I run .bootstrap from the lsh dir it succeeds but running configure prints the warnings below and make fails. checking malloc.h presence... no configure: WARNING: malloc.h: accepted by the compiler, rejected by the preprocessor! configure: WARNING: malloc.h: proceeding with the compiler's result Anyway, I attach an untested patch that shows how SSE2 or other cpu version specific optimizations can be enabled at run-time. regards, Nikos
