The libgo/sysinfo.c file includes stddef.h (for which the GCC version in ginclude is used on my system) and stdlib.h which, on musl, causes an include of /usr/include/bits/alltypes.h [1] which then defines size_t and other types, which were already defined by GCC's stddef.h, again [2]. As such, both stddef.h files are actually not included, i.e. only the GCC one is used. The alternative here would be to have libgo/sysinfo.c include the stddef.h provide by the systemc libc but not sure if that is intended here. I am personally not very familiar with the GCC codebase. I can send you a pre-processed version of sysinfo.c if you want to reproduce this yourself.
