testsuite: Update test case to comply with GCC14 changes

The test case for PR97969 needs updates in order to comply with recent
changes in GCC14.  Without these changes, failures like this can be seen
on arm-none-eabi:

.../pr97969.c:6:9: error: type defaults to 'int' in declaration of 'a' [-Wimplicit-int]
.../pr97969.c:34:1: error: return type defaults to 'int' [-Wimplicit-int]
.../pr97969.c:40:3: error: implicit declaration of function 'ae' [-Wimplicit-function-declaration]
.../pr97969.c:42:3: error: implicit declaration of function 'af' [-Wimplicit-function-declaration]
.../pr97969.c:43:7: error: implicit declaration of function 'ag' [-Wimplicit-function-declaration]
.../pr97969.c:46:10: error: assignment to 'char *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
.../pr97969.c:48:10: error: assignment to 'char *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
.../pr97969.c:50:8: error: implicit declaration of function 'setjmp' [-Wimplicit-function-declaration]
.../pr97969.c:51:5: error: implicit declaration of function 'ah' [-Wimplicit-function-declaration]
.../pr97969.c:52:5: error: implicit declaration of function 'ai' [-Wimplicit-function-declaration]
.../pr97969.c:54:5: error: implicit declaration of function 'aj' [-Wimplicit-function-declaration]

Patch has been verified on Linux.
