More on GCC

["Martin Gainty" <mgainty at hotmail dot com>]

Hello All

I managed to get 2 modules to compile. SLPReg.o has a main libslp_handle
does not have a main . But I get this always get this error
$ GCC
SLPReg.c -nostartfiles -L/cygdrive/f/slp/openslp-1.1.3/common/.libs/test
libslp_handle.o SLPReg.o
SLPReg.o(.text+0xc8):SLPReg.c: multiple definition of `_main'

Where is the extra definition of _main coming from?

Sorry for the bother,

Martin
