-Subject: [PATCH] libsmbios: fix more places with loop iterators with bad types
-
-In these cases we get:
-
-../src/libsmbios_c/smbios/smbios_obj.c: In function 'smbios_verify_smbios':
-../src/libsmbios_c/smbios/smbios_obj.c:415:31: error: comparison of integer expressions of different signedness: 'unsigned int' and 'long int' [-Werror=sign-compare]
-     for(unsigned int i = 0; i < length ; ++i )
-                               ^
-../src/libsmbios_c/smbios/smbios_obj.c: In function 'smbios_verify_smbios3':
-../src/libsmbios_c/smbios/smbios_obj.c:436:31: error: comparison of integer expressions of different signedness: 'unsigned int' and 'long int' [-Werror=sign-compare]
-     for(unsigned int i = 0; i < length ; ++i )
-                               ^
-
-I really don't understand why gcc will complain about it being signed vs
-unsigned, but not about the fact that the int can obviously overflow
-before the condition being checked against length, a larger type, is
-satisfied.
