FWIW the head now builds for arm-rtems again but the bug is still present with 15b6c83e88101ec7e2efedc114a7940cfbffa479. FWIW there are a few warnings building the ARM: ../../../../../../gcc/libgcc/config/arm/fp16.c:97:1: warning: no previous prototype for '__gnu_h2f_internal' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/config/arm/fp16.c:122:1: warning: no previous prototype for '__gnu_f2h_ieee' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/config/arm/fp16.c:128:1: warning: no previous prototype for '__gnu_h2f_ieee' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/config/arm/fp16.c:134:1: warning: no previous prototype for '__gnu_f2h_alternative' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/config/arm/fp16.c:140:1: warning: no previous prototype for '__gnu_h2f_alternative' [-Wmissing-prototypes] ../../../../../../gcc/libgcc/unwind-arm-common.inc:245:29: warning: cast discards 'const' qualifier from pointer target type [-Wcast-qual] ../../../../../../gcc/libgcc/emutls.c:159:13: warning: implicit declaration of function 'calloc' [-Wimplicit-function-declaration] ../../../../../../gcc/libgcc/emutls.c:159:13: warning: incompatible implicit declaration of built-in function 'calloc' ../../../../../../gcc/libgcc/emutls.c:171:13: warning: implicit declaration of function 'realloc' [-Wimplicit-function-declaration] ../../../../../../gcc/libgcc/emutls.c:171:13: warning: incompatible implicit declaration of built-in function 'realloc'
