netCDF 2.4 beta1

[pack@xxxxxxxxxxxx (Daniel Packman)]

I found that installation of this release on an ibm aix 4.1.3 system
failed to create ncgen because STREQ was undefined in ncgentab.c
This, in turn, is created from ncgen.y. I just added

#define STREQ(a, b)     (*(a) == *(b) && strcmp((a), (b)) == 0)

to the start of ncgen.h and then all compiled fine. Perhaps someone can
explain how this definition is supposed to get resolved.
