Subject: Possible CRLF and -mno-cygwin bugs
X-mailer: msmail-1.0 by Emmes Technologies <http://www.emmestech.com>

     After a rocky start, I have had reasonable success with Cygwin-1.1.4
(thanks to Chris Faylor for helping me get started).  I have, however, found two
slight problems which I believe, if fixed, would enhance Cygwin.

     The first involves the old issue of carriage returns and line feeds: Many
programs having ^Ms as the next-to-last character on a line compile just fine.
However, I have noticed two problems.  The first is that in .c and .h files
"\^M^J" is not recognized as a continuation symbol as I believe it should be.
The second problem is that "#define FIRST Mark^M^J" defines "FIRST" as "Mark^M",
whereas I think it should be defined as "Mark".

The second problem I have found involves the -mno-cygwin option.
First consider the +Cygwin part which works fine:

/usr/include/pwd.h mentions uid_t and #includes <sys/types.h> which typdefs it. 

Now the -Cygwin part:

On my machine, the -mno-cygwin system include path is:
 ..
 .
 /usr/include/mingw32
 /usr/include/mingw
 /usr/lib/gcc-lib/i686-pc-cygwin/2.95.2/../../../../include
 /usr/include
 /usr/lib/gcc-lib/i686-pc-cygwin/2.95.2/include
 /usr/include

     This means that "pwd.h" comes from "/usr/include" just as for +Cygwin, but
"sys/types.h" comes from "/usr/include/mingw".  The "types.h" file in
"/usr/include/mingw/sys", unlike its counterpart in "/usr/include/sys", does not
typedef uid_t, which leads to compiler errors such as:

In file included from metamail.c:42:
/usr/lib/gcc-lib/i686-pc-cygwin/2.95.2/../../../../include/pwd.h:61: warning: parameter names (without types) in function declaration
/usr/lib/gcc-lib/i686-pc-cygwin/2.95.2/../../../../include/pwd.h:65: parse error before `struct'

     Unless there are countervailing reasons, it seems to me that
"/usr/incude/mingw/sys/types.h" should include the line

   typedef int uid_t;

and possibly also include

   typedef int gid_t;
   typedef int dev_t;
   typedef int ino_t;
   typedef int mode_t;
   typedef int caddr_t;

which likewise appear in "/usr/include/sys/types.h".
