On an i386 platform with no rt_sigsuspend syscall (ie: Linux 2.0), compilation will halt on libc/sysdeps/linux/common/sigsuspend.os with a cryptic error message:

I've investigated and found that the cause is that a literal '0' is being passed into a block of complex assembler macrology that is only prepared to deal with register names - '%eax', etc.
In turn, that seems to be because of a typo in the GCC register constraints. The constraints for 2 and 3-argument syscalls includes a "C" constraint. To gcc, "C" means an SSE floating point constant -- an unlikely element in a syscall. I suspect the author meant to type "S" (%esi).

(spotted by Peter S. Mazinger <ps.m@gmx.net>)

make regex_old.c, ruserpass.c use __uc_malloc,
replace "buf = malloc(BUFSIZ); if (!buf) abort();" by __uc_malloc
elsewhere.
With last 7 patches together uclibc has 3k of static data total
with fairly big .config and with 2k being used for 2 x BUFSIZ stdio buffer:

introduce __uc_malloc, so that users can intercept libc internal OOM.
