Bash fails on BerkeleyDB configure

[Howard Chu <hyc at highlandsun dot com>]

I ran into this problem while trying to run the BerkeleyDB 4.6.21 configure 
script with current Cygwin installed on a Windows64 machine. (Windows 2003 
Server SP2 x86_64, using the Cygwin build of the x86_64-pc-mingw32 compiler 
from the mingw-64 project).

The script fails on a case statement. Pasting the case statement into a 
separate script by itself doesn't fail, so I can't send you a simple test 
case. But you can easily download the BerkeleyDB source code to reproduce the 
problem. The first failure starts at line 28024:

if test $ac_cv_type_u_int8_t = yes; then
  :
else

    case "1" in
    "$ac_cv_sizeof_unsigned_int")
        u_int8_decl="typedef unsigned int u_int8_t;";;
    "$ac_cv_sizeof_unsigned_char")
        u_int8_decl="typedef unsigned char u_int8_t;";;
    "$ac_cv_sizeof_unsigned_short")
        u_int8_decl="typedef unsigned short u_int8_t;";;
    "$ac_cv_sizeof_unsigned_long")
        u_int8_decl="typedef unsigned long u_int8_t;";;
    "$ac_cv_sizeof_unsigned_long_long")
        u_int8_decl="typedef unsigned long long u_int8_t;";;
    *)
        if test "" != "notfatal"; then
            { { echo "$as_me:$LINENO: error: No unsigned 1-byte integral 
type" >&5
echo "$as_me: error: No unsigned 1-byte integral type" >&2;}
   { (exit 1); exit 1; }; }
        fi;;
    esac
fi

ac_cv_sizeof_unsigned_int is defined to 4 by prior tests. Likewise,
ac_cv_sizeof_unsigned_char is 1
ac_cv_sizeof_unsigned_short is 2
ac_cv_sizeof_unsigned_long is 4
ac_cv_sizeof_unsigned_long_long is 8

The test fails with "No unsigned 1-byte integral type". The script exits at 
that point. Getting past this (by explicitly setting variables to bypass the 
test) just runs into another failure as the script uses the same construct to 
set a bunch of other type defs.

Let me know if you need any more info.
