 # Fix paths reported by the libIDL-config-2 tool to conform with Fedora
 # multilib installation paths:
-Patch0:         libIDL-0.8.6-multilib.patch
+Patch:          libIDL-0.8.6-multilib.patch
 # Remove an unused parent-node variable in the primary_expr part of the parser,
 # which caused a compiler warning.
-Patch1:         libIDL-0.8.14-parser-primary_expr-unused-parent-node.patch
+Patch:          libIDL-0.8.14-parser-primary_expr-unused-parent-node.patch
 # On platforms (such as 64-bit Linux), where long long int and long int are
 # both 64-bit, we can have IDL_LL defined to ll (format with %%lld) while
 # IDL_longlong_t, which is just gint64, may be ultimately defined to long int.
 # This results in compiler warnings about the mismatch between the long long
 # format and long parameter, even though the types are compatible. We can fix
 # this with a cast to (long long) before formatting.
-Patch2:         libIDL-0.8.14-long-long-format-warnings.patch
+Patch:          libIDL-0.8.14-long-long-format-warnings.patch
 # Instead of type-punning with sscanf, parse into a temporary with a type
 # matching the format code and then memmove into the “integer” storage. This is
 # no less platform-dependent, but does not invoke undefined behavior or produce
 # a compiler warning.

 # Fix references to the old libIDL-config script by changing them to
 # libIDL-config-2.
