I would not worry about it too much, if you have a look at the comments in the .h file enquire generates you will see that the errors that it has detected are rather infesteminal (ie the order of 1e-308) so I suspect the rounding is wrong rather than anything else more serious. Apart from that gcc 2.3.2 works fine, I have compiled X with it with only one problem, in /usr/include stdlib.h there is the following ifdef: #if defined(alloca) && (alloca == __builtin_alloca) void *alloca __P((int)); /* built-in for gcc */ #else void *alloca __P((size_t)); #endif /* __GNUC__ */ You have to comment out the definition of alloca like this: #if defined(alloca) && (alloca == __builtin_alloca) /* void *alloca __P((int)); /* built-in for gcc */ #else void *alloca __P((size_t)); #endif /* __GNUC__ */ Otherwise gcc gets confused and will not use the builtin alloca. Apart from this X compiles without a hitch and it seems (to me at least) a bit faster (not much) and a little bit smaller (again not much). I have not found any problems with commenting out the alloca definition but I am not happy about doing it, anyone got a better suggestion?
