R-1.7.0 'make check' fails on reg-tests-1
You appear to have a problem with the accuracy of the arithmetic on that machine. Please run the test by hand and tell us what N and max(dd) are when the test fails (or is it the mvftt test?) The test is not new, but the change in random-number generator will affect what values are tested.

Dear all, I am trying to upgrade R-1.6.2 to R-1.7.0 on an SGI running IRIX6.5. Everything compiles but I get an error in the testing phase: [snip] running regression tests make[3]: Entering directory `/usr/local/src/R-1.7.0/tests' running code in 'reg-tests-1.R' ...make[3]: *** [reg-tests-1.Rout] Error 1 make[3]: Leaving directory `/usr/local/src/R-1.7.0/tests' make[2]: *** [test-Reg] Error 2 make[2]: Leaving directory `/usr/local/src/R-1.7.0/tests' make[1]: *** [test-all-basics] Error 1 make[1]: Leaving directory `/usr/local/src/R-1.7.0/tests' make: *** [check] Error 2 this is the part in reg-tests-1.Rout.fail which fails:

Any help concerning this matter would be very much appreciated.
