I’m working with Cygwin in Windows XP (through virtual machine), with a legacy project that I was given to try figuring out. When trying to build the code (several snapshots/revisions), it fails when trying to link the thousands of .o files. I get the error:

make: execvp: C:projecttoolsmaketool.exe: Argument list too long

The command in the script is basically like
maketool.exe (long list of arguments including the tons of .o files)

It’s apparently a hard limit set by the OS. I was told these code snapshots were able to be built back in the day (nearly 20 years ago from now). But there’s no documentation, so I’m trying to figure out what my options are. What can be done to get around this?
