Subject: [PATCH 06/25] [gdb/testsuite] Use -std=c99 in gdb.base/nodebug.exp
|
||
|
|
|
||
|
|
With test-case gdb.base/nodebug.exp I run into:
|
||
|
|
...
|
||
|
|
gdb compile failed, gdb.base/nodebug.c: In function 'multf_noproto':
|
||
|
|
gdb.base/nodebug.c:63:1: warning: old-style function definition \
|
||
|
|
[-Wold-style-definition]
|
||
|
|
63 | multf_noproto (v1, v2)
|
||
|
|
| ^~~~~~~~~~~~~
|
||
|
|
...
|
||
|
|
|
||
|
|
Fix this using -std=c99.
|
||
|
|
|
||
|
|
Tested on x86_64-linux.
