23 # - On IRIX 6.5 with CC="cc", the run time search patch must not be longer
24 # than 256 bytes, otherwise the compiler driver will dump core. The only
25 # known workaround is to choose shorter directory names for the build
26 # directory and/or the installation directory.

29 # which needs '.lib').
