testsuite: c++: Allow for std::printf in g++.dg/modules/stdio-1_a.H [PR98529]
g++.dg/modules/stdio-1_a.H currently FAILs on Solaris:
FAIL: g++.dg/modules/stdio-1_a.H -std=c++17 scan-lang-dump module "Depset:0 decl entity:[0-9]* function_decl:'::printf'"
FAIL: g++.dg/modules/stdio-1_a.H -std=c++2a scan-lang-dump module "Depset:0 decl entity:[0-9]* function_decl:'::printf'"
FAIL: g++.dg/modules/stdio-1_a.H -std=c++2b scan-lang-dump module "Depset:0 decl entity:[0-9]* function_decl:'::printf'"
The problem is that the module file doesn't contain
Depset:0 decl entity:95 function_decl:'::printf'
as expected by the test, but
Depset:0 decl entity:26 function_decl:'::std::printf'
This happens because Solaris <stdio.h> declares printf in namespace std
as allowed by C++11, Annex D, D.5.
This patch allows for both forms.
Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and
x86_64-pc-linux-gnu.
