Hi, my project uses a mixture of C and Fortran functions by translating Fortran to C with f2c, compiling the generated sources into a library, and linking the rest of the project to that library. For this scheme to work, the executable also needs to be linked with g2c *or* with f2c. Under most circumstances g2c is preferred. The problem is that there is a bug in libg2c that causes a segfault on some processors, i.e. dual core opterons and some 64bit intels; see: http://people.debian.org/~terpstra/message/20070906.195243.618bfaf4.en.html For these processors I would like to have the build system fall back on "-lf2c -lm". I would like to ask for advice on how to implement this test in autoconf. Since there is no list of affected processors, I don't really know which processors would segfault with g2c and I can't switch on the target. I would instead like to execute the test similar to the one in the bug report above that would pass for most processors but cause a segfault on the affected few. The ones that exhibit a segfault need to be linked against libf2c.
