Subject: cygwin-1.1.2: printf("%e") broken

Hello,

having updated to cygwin-1.1.2, I now experience the following
problem that printf("%e") seems to be broken:

  - very small C program printf_bug.c:

          #include <stdio.h>
          int main()
          {
            double d=0.0;
            printf ("%f   %e\n", d, d);
          }

  - compile as "gcc -o printf_bug printf_bug.c"

  - executing the file printf_bug.exe using cygwin1.dll version
    1.1.2(0.21/3/2) 2000-06-06 22:20 results in the corrupt output

       0.000000   0.      e+00

    (in hex, the output of %e is 30 2e 00 8d b6 00 00 00 65 2b 30 30)

  - if, however, I replace the file cygwin\bin\cygwin1.dll by the
    version 1.1.0(0.17/3/2) 2000-03-01 00:15:19 then executing
    the file printf_bug.exe (no recompilation, just cygwin1.dll
    exchanged) results in the correct output

       0.000000   0.000000e+00

    (in hex, the output of %e is 30 2e 30 30 30 30 30 30 65 2b 30 30)

Any ideas?

Ulrich
