No idea. I just know that FPC doesn't use GCC. I think it doesn't even
link to libc! (I can't really confirm, ldd crashes on the executable
produced by fpc.) Maybe it just avoids some constant overhead due to
this.
If that's the root, then it may well be a fictitious benefit because it may
well have no effect on the resident set size (the amount of RAM actually
used) during the main processing. All that it would be doing is to no include
at all code that the C version never pulls off disk (executables lazy load
on most systems).
