dnl Check for the presence of the Sun Studio compiler.
|

|
|
dnl If Sun Studio compiler is found, set appropriate flags.
|
||
|
|
dnl Additionally, Sun Studio doesn't default to 64-bit by itself,
|
||
|
|
dnl nor does it automatically look in standard Solaris places for
|
||
|
|
dnl 64-bit libs, so we must add those options and paths to the search
|
||
|
|
dnl paths.
|
||
|
|
|

|
|
dnl TODO(kenton): This is pretty hacky. It sets CXXFLAGS, which the autoconf
|
||
|
|
dnl docs say should never be overridden except by the user. It also isn't
|
||
|
|
dnl cross-compile safe. We should fix these problems, but since I don't have
|
||
|
|
dnl Sun CC at my disposal for testing, someone else will have to do it.
