[Gdal-dev] Solaris build with static proj4.

[Frédéric Trastour]

Hello,

version 1.2.3 has the same configure problem than the previous ones ( since 1.2.0 ) regarding the static link of
the PROJ4 Library.

Only the first possible directory is tested and the result is cached.

Here is a patch for the configure.in file.

Do you plan to integrate it for the future ?

Regards.
