I can't find any statements on the Guile pages about portability: what operating systems does it support, how well are they supported, etc.?
Before I started using Guile I naively assumed it was basically just a parser and so it was almost trivially very portable. Now that I see all the advanced features and capabilities it strikes me that Guile is not nearly so easily ported to non-POSIX-style systems as I assumed. The docs say it's "the official language for the GNU operating system", but what about non-GNU OS's, such as AIX/Solaris/HP-UX, the various BSD's, or Windows, or MacOS, or even more specialized environments like OpenVMS, AmigaOS, etc.? Cheers!
