STREQ is just a macro defined on line 8 of ncgen.l, and this is enough to
get it defined for most compiling environments, but apparently not for the
HPUX/gcc platform you are using.  Here are three alternative workarounds:

 1. Use the more recent version (2.4.1) netCDF found at

      ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.Z

    In this version, the STREQ definition has been moved to the top of the
    ncgen.y file, where it also works fine.

 2. Copy the STREQ definition to near the top of ncgen.y, right before the
    definition of the YYSTYPE macro and invoke "make" again.

 3. Use the native cc and yacc that come with HPUX instead of gcc/bison
    (this may involve changing your PATH variable and rerunning the
    "configure" script).
