4.3 regression with netcdf library

[Florian Ladstaedter]

Hi, the netcdf 3.6.2 library (source available from 
http://conan.unidata.ucar.edu/downloads/netcdf/netcdf-3_6_2/index.jsp) 
can be compiled with gfortran 4.2.1 without problems:


----------------------------
FC=gfortran-4.2  CPPFLAGS=-DpgiFortran ./configure
make
make check
----------------------------

works nicely.

However with 4.3.0 20070730 I get an error message while compiling:


----------------------------

----------------------------


The problem seems to be related with a different output of the configure 
script:


4.2.1:
-------------------------------------
checking for Fortran "byte"... yes
checking for Fortran "integer*2"... yes
checking if Fortran "byte" is C "signed char"... yes
checking if Fortran "byte" is C "short"... no

Since this seems to be related to the -dev version of gfortran I post 
this here and not at the netcdf list. Not much information though I 
admit. Please find the sources at the link provided.
