Mumit Khan's port of gcc-2.95 for Cygwin failed to compile the following
simple subroutine with the command "gcc -v -O2 -mno-cygwin -c mdate.c -o
mdate.o".
#include <sys/time.h>
char *mdate()
{
time_t ts;
char *ntime, *ctime(), buf[100];
int ni;
time(&ts);
ntime = ctime(&ts);
strcpy(buf,ntime);
ni= strlen(buf);
buf[ni-1] = '\0';
strcpy(ntime,buf);
return (ntime);
}
Output from the compile is as follows:

I am running the standard full version of Cygwin-b20.1 under Windows98 on
my HP Pavilion PC. Cygwin-b20.1 gcc compiles the above without complaint.
Both Cygwin-b20.1 and Khan's port compile the above if the "-mno-cygwin"
parameter is omitted. Also, gcc-2.95 compiles the above, without -mno-cygwin
obviously, under HP-UX 10.20 on a HP workstation.
