Yes, that's the error message I get when compiling...

P:\>make dsweep
gcc -Wall -o dsweep.exe -Lc:\tdt\drivers\apos\c\ -Lc:\tdt\drivers\xbdrv\c\
dsweep.o rglio.o -lgpp -lm
c:/djgpp/lib/crt0.o(.data+0x92):crt0.s: undefined reference to `main'
c:/djgpp/lib/libc.a(crt1.o)(.text+0x312):crt1.c: undefined reference to
`main'
make.exe: *** [dsweep] Error 1

It's not just that I've misdefined "main", either - I'm using the vanilla
"int main(int argc, char *argv[])".

In any case, nm shows that main is defined in the object file, the
relevant line of nm's output being
000000d0 T _main

so what've I done?
