Subject: [PATCH] build: Avoid warnings about unknown pragmas.
|
||
|
|
|
||
|
|
In commit 4bbbf03b8bc266ed2b63c461cd0945250bb134fe we started to
|
||
|
|
ignore bogus GCC 11 warnings. Unfortunately earlier versions of GCC
|
||
|
|
don't know about those pragmas so give warnings [hence errors in
|
||
|
|
developer builds] like:
|
||
|
|
|
||
|
|
tsk.c:75:32: error: unknown option after '#pragma GCC diagnostic' kind [-Werror=pragmas]
|
||
|
|
|
||
|
|
Turn off these warnings.
|
||
|
|
|
||
|
|
Updates: commit 4bbbf03b8bc266ed2b63c461cd0945250bb134fe
|
||
|
|
