It all started so innocently... I wanted to get "./microperl -Ilib -V" working in Tru64. Which it wouldn't, since the ivsize et alia were all wrong since Alphas are not Intels (though these days Intels are Alphas, if you squint appropriately). So now there's a Makefile.micro make target, patch_uconfig, that using your current Perl patches up uconfig.sh just a little so that there's a slightly larger change of your non-x86 platform building a slightly more functional (or a slighty less core-dumping) microperl. But while doing that I found that I had back when submitted a slightly broken Porting/checkcfgvar.pl. Now fixed, and missing config vars sprinkled into various platform-specific config files. ('undef' is usually a safe bet for the d_xxx variables, for example.)Thread Next
