Microsoft C compilers going back to at least version 5 have supported
the gmtime call. We use Microsoft C Version 6.0 on OS/2 systems here
at Unidata to produce 16-bit executables linked against the netCDF library.
We will soon be using the GNU C compiler, gcc, coupled with an emulation
environment for OS/2 2.x to build 32-bit versions of netCDF routines.
