The 'DEBUG_GCC4._(AARCH64|ARM)_CC_FLAGS' settings do not pass the
-Wno-unused-but-set-variable option to the compiler.
(See
egrep '(DEBUG|RELEASE)_GCC4._(AARCH64|ARM)_CC_FLAGS' Conf/tools_def.txt
)
Consequently, recent commit SVN r16499 ("MdeModulePkg: Update the device
path info for the storage when former drivers not provide it.") breaks such
builds with the following error message:
MdeModulePkg/Universal/SetupBrowserDxe/IfrParse.c:
In function 'IsDevicePathExist':
MdeModulePkg/Universal/SetupBrowserDxe/IfrParse.c:469:14:
error: variable 'PathHdr' set but not used
[-Werror=unused-but-set-variable]
EFI_STRING PathHdr;
^
cc1: all warnings being treated as errors
Eliminate the variable.
