Adding GAUSS_PDF and GAUSS_CVF functions

Avoid a warning with Intel C++ due to a pragma only understood by g++

typo, pragma written twice.

Make GDL compile on HP-UX with GCC. Workaround for missing GLOB* and use of the POSIX function putenv() instead of setenv()

Type qualifier on return type is meaningless. Removes some warnings with Intel C++ compiler.

Integration of some patches from tthierry. I've not integrated the patch for pythongdl.cpp as it doesn't apply cleanly and i've not integrated the configure patch also. It compiles correctly with g++ and Intel C++.

Implementation of t_pdf. Rework of the Laguerre function now much shorter.
