It was me, yes. And I used to know from what end you have to approach a Windows machine. :-) But not to the point of knowing exactly how to change fork() and sbrk(), (and mmap()) into whatever functions with 15 arguments you have to use on Win32 as their replacements (they already have about 10 versions of spawn to use in place of fork). Note that since 2005 GAP has changed quite a bit, too. They made a go at making it multithreaded (HPC GAP), and that made code harder to deal with (HPC GAP is still beta). Instead of GAP's native GC (with its sbrk/mmap), HPC GAP uses Boehm GC, which does run on native Windows. But it's a beta... Oh, and someone died porting GAP to Windows, some years ago.
