When running Enquire.efi, several errors similar to the following are produced:
Maximum exponent = 128
Maximum number = 3.40282347e+38
*** WARNING: Possibly bad output from printf above
expected value around 3.40282347e38, bit pattern:
11111111 11111111 01111111 01111111
sscanf gave -inf, bit pattern:
00000000 00000000 10000000 11111111
difference= inf
Overflow doesn’t seem to generate a trap
The memory allocation tests will also fail, sometimes leaving all available memory consumed.
The correct output in the above example is:
Maximum exponent = 128
Maximum number = 3.40282347e+38
Overflow doesn't seem to generate a trap
The root cause is that all operations on values of Long or ULong type, within the gdtoa library, must be 32-bit operations. A previous change replaced the Long and ULong definitions with INTN and UINTN, respectively. While this is correct for a lot of Linux and NetBSD code, it was not correct for this library.
This fix reverts the definitions of ULong and Long back to 32-bit types.
A descriptive comment has also been added to the U union.
Additional white-space has been added to tidy up the definitions of the word0 and word1 macros.
Verified with Enquire.efi and the ISO/IEC C Library compliance Validation Suite.

ISSUES.txt: Added issue 11, updated status of issue 1.
gdtoa/gdtoaimp.h: Fix definition of union U.
Locale/_wcstod.h: Return 0.0 instead of 0 in the "no_convert" case.
Locale/multibyte_Utf8.c: In wcsrtombs(), if both the destination pointer is NULL and the size, Limit, is 0; return the estimated length of the converted string up to ASCII_STRING_MAX bytes.

This set of three packages: AppPkg, StdLib, StdLibPrivateInternalFiles; contains the implementation of libraries based upon non-UEFI standards such as ISO/IEC-9899, the library portion of the C Language Standard, POSIX, etc.
AppPkg contains applications that make use of the standard libraries defined in the StdLib Package.
StdLib contains header (include) files and the implementations of the standard libraries.
StdLibPrivateInternalFiles contains files for the exclusive use of the library implementations in StdLib. These files should never be directly referenced from applications or other code.
