I have Gambit 4b17 and I cannot compile syntax-case.scm with gcc 4.0 for some reason. It sits there forever doing something and gcc eats up 700Mb+ of memory. I'm on Mac OSX 10.4.4.
On my machine (dual 2GHz G5 with 8GB of RAM running Mac OS X 10.4.4):

So, yes, it will take a long time to compile, it's an 8MB C source file consisting of one C function (and even if --enable-single-host is not specified, the largest part of syntax-case.c is still one C function).
If you want to save a bit of time or space during the compile, you could add -D___OPTIMIZE_SPACE to the command line in gsc-cc-o wherever you installed gsc and gsi. Or, you could copy gambit.h to the local directory where you're trying to compile syntax-case.scm and add the define there:
[lindv2:~/Desktop] lucier% cp /usr/local/Gambit-C/include/gambit.h . [lindv2:~/Desktop] lucier% vi gambit.h [lindv2:~/Desktop] lucier% diff -p /usr/local/Gambit-C/include/ gambit.h gambit.h *** /usr/local/Gambit-C/include/gambit.h Thu Jan 19 15:17:50 2006 --- gambit.h Wed Jan 25 13:03:48 2006 *************** *** 1192,1197 **** --- 1192,1198 ---- * Determine optimization goal. */

Even then, I noticed that cc1 temporarily required 1.25GB of memory near the end of the compilation (just by monitoring top as cc1 ran).
