    initial v1  
    11Is it for a good reason that `gcc-4.2` is not blacklisted, despite the statement above: “Don't try to build with GCC 4.2 or 4.3 … requires absurd amounts of RAM”?

     3The build makes this warning:
     4{{{
     5***                                                                    ***
     6*** The GCC compiler that is being used has problems compiling Gambit  ***
     7*** generated code when the normal set of C compiler optimizations are ***
     8*** enabled and the configure flag "--enable-single-host" is           ***
     9*** specified.  It can take over 20 GB of virtual memory to            ***
     10*** compile some files.  For this reason the GCC compiler optimization ***
     11*** which performs loop invariant code motion has been disabled by     ***
     12*** adding the GCC command line option "-fno-move-loop-invariants".    ***
     13*** This greatly reduces compile time space requirements and it has a  ***
     14*** small impact on overall run time performance, but for some tight   ***
     15*** loops the effect is larger.  If you want to avoid this problem     ***
     16*** then upgrade your version of GCC to 4.4 (or above hopefully) or    ***
     17*** downgrade to a version prior to 4.2 .                              ***
     18***
