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