We're porting a program from cc to gcc, and need to maintain a structure
packed on byte boundaries (compiled using the #pragma pack(1) in cc).  What is
the GCC equivalent method of turning this on and off?  At present the structure
elements are being padded which causes the data file format to change, breaking
the program.  :-(  Any help gratefully appreciated.
