Summary: feature or Bug with Turbo_C


I encountered two problems during the process of converting a program 
from MSC 3.0 to Turbo_C and I don't know if they are bugs or features.

The first problem (please don't flame me for this one, I inherited this
code) occurred because Turbo_C, unlike MSC 3.0, requires the argument types
of functions to be declared.  MSC requires a function declaration
if the function returns something other than an int while Turbo_C requires this
and  the declaration for all arguments.  For example in MSC 

char *strswap();       /* in calling routine */



char *strswap(a,b,count);     /* start of subroutine strswap */
char *a,*b;
int count;
{
...
}


would be required while in Turbo_C

char *strswap(char *a,char *b,int count); /* in calling routine */


char *strswap(char *a, char *b,int count); /* start of subroutine strswap */
{
....
}

would be required.


I haven't decided if this requirement is an indication of a smart compiler or
a dumb one but the explicit declarations did allow Turbo_C to turn up some
errors that MSC missed.



The second problem I encountered involved the way MSC and Turbo_C deal with
command lines. If the following command were given at the DOS prompt:

C>test b="this is a test"

MSC considers argv[1]='b="this is a test"' and argv[2]='' while Turbo_C 
considers argv[1]='b=' and argv[2]='this is a test' (Note: Turbo_C did 
eliminate the quotation marks as I have indicated).  Which, if either 
of these, is correct?


Are these bugs or features?  I looked in K&R but I couldn't find a thorough
explanation of either of these points.
