Build failure with gcc15

[micwoj92]

Hello,
Trying to build naemon 1.5.0 (1.4.4 fails too) with gcc 15.2.1 20260209 fails with following error message:

src/naemon/checks.c: In function 'parse_output':
src/naemon/checks.c:114:19: error: assignment discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]

      |                   ^

i am unable to reproduce this issue.

even added

AX_CHECK_COMPILE_FLAG([-Wdiscarded-qualifiers], AM_CFLAGS+=" -Wdiscarded-qualifiers")

to the configure.ac.

%>gcc --version
gcc (Debian 15.2.0-12) 15.2.0

Is there anything else you did to compile naemon?
