Compiling with VC7

LINK : warning LNK4224: /DEBUGTYPE:BOTH is no longer supported; ignored

Same here.

/DEBUGTYPE:BOTH is added by rntcl, so that is not a Nettle problem. I'll clean that up when VC7 compiles something.

cl : Command line warning D4027 : source file 'aes.s' ignored cl : Command line warning D4021 : no action performed

aes.s is an assembler file, produced by passing aes.asm through m4 (this particular assembler file is also a dummy, needed only for preventing compilation of aes.c, but that's probably irrelevant). What compiler command and options do you need to process assembler files with rntcl and/or cl?

cl.exe /? reveals no flags that would force assembler compilation, but I assume they are in there somewhere.
