How can I specify a wildstar to add a bunch of .obj's into a lib, using lib? Also, lib has the same name as MS's lib command, therefore creating a conflict.

Given code such as follows:
void foo(); // No prototype, just a declaration
int main()
{
foo(99); // Expects at least foo(int)
foo("hi"); // Expects at least foo(char *)
return 0;
}
sc will diagnoses:
foo("hi");
^
syn.c(6) : Error: need explicit cast for function parameter 1 to get
from: char *
to : int
--- errorlevel 1
Clearly this is undefined behavior, but in case where say
the arguments were pointers to function of different types
the danger is minimal, especially when done on purpose.
Therefore, I feel the the above is too strong an error message.
Is there an option to control it?

Microsoft changed their .obj file format from OMF to COFF. The DM compilers still generate OMF, which Microsoft's tools cannot handle anymore. MS made the switch when they abandoned 16 bit support. It's necessary to use the DM linker and DM lib with the output of DMC++. You'll need to adjust PATH so /dm/bin precedes Microsoft's tools bin. It isn't necessary to adjust INCLUDE, etc., because sc.exe will pull it out of \dm\bin\sc.ini.
