37 # Known limitations:
38 # - On IRIX 6.5 with CC="cc", the run time search patch must not be longer
39 # than 256 bytes, otherwise the compiler driver will dump core. The only
40 # known workaround is to choose shorter directory names for the build
41 # directory and/or the installation directory.
43 # All known linkers require a `.a' archive for static linking (except M$VC,
