Why shouldn't it? What does --print-libgcc-file-name return on the hurd? > I suggest to try: > > "dpkg --print-installation-architecture" if not cross-compiling and dpkg > is available, which should always be correct, and is the only sensible > way without duplicating "arbitray" conversion code from dpkg. There are two things being set here, the first is the arch string for dpkg and the next is the byte sizes for the MD5 code, it is important to not munge up either. > For cross compilation, the gcc trick is a good approximation, but please > don't strip off -whatever, but check if it is linux or gnu, or even better, > use full gnu system type names in the archtable: > > i386-linux i386 i486 > i386-gnu hurd-i386 i486 What you really need here is a seperate setting that indicates what the OS is, it would be nicer than trying to munge the arch string. What could be done is to write a detection rule for hurd/linux/etc and have that create a sepeare entry in config.h, it could then munge it internally to generate the correct test for whatever todays arch/system standard is. I like having the arch transforms as a seperate operation from system type transforms, that seems to make more sense. > BTW, can pthreads be made optional?

As long as the C library does not declare it has pthread support by defing _POSIX_THREADS then everything will be OK. The GUI library does/did/might require pthreads but that isn't compiled by default anymore I'm not terribly good with hacking configure/autoconf, if you could implement a good patch for the system type that would be very nice. Sounds like all that is needed is to save the -foo part after the arch string and write that to the config file. Jason
