I didn't realize my reply to Mikael was off the list - here's a possible fix.  I'm still not sure if it's OSX10.10 specific or not:

Thanks - you only need to change the value in 'configure' (and 'configure.ac' for a full autotool rebuild), and it does now work - not sure if this is an error in the configure script or OS X 10.10 specific.  

checking for struct stat64... yes

checking for posix threads with CFLAGS=' ' and LIBS=' '... yes

checking for thread local storage class... __thread

Adam, can you replace all occurrences in your Gambit sources of "pthread_join (&thread, NULL);" with "pthread_join (thread, NULL);" and check again?

I'd like to try out the multiple vm option as I want to have 2 separate OS threads, each running their own copy of gambit - neither of which need to communicate with the other, so I tried to rebuild Gambit using the --enable-multiple-vms option (this is under OS X 10.10 - Yosemite with Xcode6 - 6A313):

quorra:gambit aking$ ./configure --enable-multiple-vms --enable-cplusplus

It ends up showing the following warning:

checking for struct stat64... yes

checking for posix threads with CFLAGS=' ' and LIBS=' '... no

checking for posix threads with CFLAGS=' -mt' and LIBS=' '... no

checking for posix threads with CFLAGS=' -pthread' and LIBS=' '... no

checking for posix threads with CFLAGS=' ' and LIBS=' -lpthread'... no

checking for win32 threads... no

configure:

I know I have pthreads installed and working as I have 3 different apps all using pthreads on this system.  Not sure what's going wrong here - pthread's API change?
