Well, the newer gcc 3.4.3 that you are using is also having problems - that the older one did not have: ../../gltests/test-frexpl.c:144: assertion failed ../../gltests/test-ldexpl.c:130: assertion failed > maybe autoconf should default to cc on this platform, rather than always > favoring gcc. I disagree. I've built many packages with that compiler on IRIX, without problems. The problem is more with the "long double" area - which is not much used by other program, hence less reliable - than with gcc. Any kind of rarely used features, be it global register variables, OpenMP support, or similar, has more bugs than average features. > Should we update install.texi (and thus INSTALL) to mention > that on Irix, if gcc doesn't work, to try cc? Certainly not. It would make people doubt of gcc's quality. And gcc - especially since version 4.0 - is of outstanding quality and reliability. Bruno
