Not automatic just toyed a bit with the different cpu models various optimizations, does not help a bit though if the code cant make use of features like say SSE either because its not coded for that or incompatible.
64 bit build and yes it works
actually only one place where the 64 bit compiler says no and its in resid-fp not in PCem itself, so i had to compile with -fpermissive to create it but it seems to work so far
(might not work on AMD its compiled with intel instructions). Ill make one for AMD also.
i also created a codeblocks project for the source, the maintainer is welcome to use it.
Productivity is a state of mind.
