  22 # Known limitations:
  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.

  28 # All known linkers require a `.a' archive for static linking (except M$VC,
  29 # which needs '.lib').
