16# The first argument passed to this file is the canonical host specification,
17#    CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
18# or
19#    CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
20# The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld

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

31# All known linkers require a `.a' archive for static linking (except MSVC,
32# which needs '.lib').
