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

| # The set of defined variables is at the end of this script. |
| |
| # Known limitations: |
| # - On IRIX 6.5 with CC="cc", the run time search patch must not be longer |
| # than 256 bytes, otherwise the compiler driver will dump core. The only |
| # known workaround is to choose shorter directory names for the build |
| # directory and/or the installation directory. |
| |
| # All known linkers require a `.a' archive for static linking (except MSVC, |
| # which needs '.lib'). |
