In my defense, here was the failure in ./configure before the patch, using
gcc 3.4.4:
configure:23953: checking whether sigsetjmp() links okay
configure:23981: gcc -std=gnu99 -o conftest.exe -O2 -pipe conftest.c
- -ldl >&5
conftest.c: In function `main':
conftest.c:48: error: invalid lvalue in unary `&'
configure:23987: $? = 1
configure: failed program was:
| /* confdefs.h. */
| #define PACKAGE_NAME "GNU AutoGen"
...
| /* end confdefs.h. */
| #include <setjmp.h>
| int
| main ()
| {
| sigjmp_buf bf;
| return sigsetjmp(&bf,0);
| ;
| return 0;
| }
configure:24007: result: no
Removing the unary & fixed the configure test.
