Subject: [PATCH] libs/src/portable: fix build w/ gcc-14
Building xinetd with gcc-14 in Buildroot raises the following error:
cvt.c: In function 'fcvt_r':
cvt.c:113:9: error: implicit declaration of function 'strx_nprint' [-Wimplicit-function-declaration]
113 | n = strx_nprint (buf, len, "%.*" FLOAT_FMT_FLAG "f", ndigit, value);
| ^~~~~~~~~~~
Including "str.h" header to fix the compiler error would add a
build-time dependency of libportable on libstr, creating a circular
dependency chhain:
libportable -> libstr -> libsio -> libportable
which results in GNU make dropping dependency edges and therefore not
fixing the original build error.
The commit keeps the existing library layering unchanged while restoring
successful builds with modern compilers.
