Hello,
Yes, the limit used by POMAKE is 1000. If the command line is longer, I create an "argument file" and change the syntax to: cmd @argfile. This assumes that "cmd" (POCC in this case) can handle @filename, which it can't - but the compiler driver, CC, can. You could change this from POCC ... to CC /c ...
I can't find the limit at the moment, but I think this was done because of a limitation for command lines in some Win 9X version. If it was a bit longer, probably 1024, it was truncated. Probably not an issue on Win NT/2K/XP, and maybe not even on Win 98. I will have to investigate...
