Hi,

I notice DJGPP/GCC generates by default, 4 bytes aligned
structures. Currently, I need at least 2 of my structures are
packed (no holes). I read the manual about a compiler option to
do this, but it will generate ALL structures as packed. I only
need 2 (or several more) structures packed, and others are
aligned. How can I do this? Are there any preprocessors that can
be used to tell the compiler if I want a specific structure to
be packed and else to be aligned?

BTW, anybody knows where I can find a documentation of all C/C++
preprocessors?
