Hello, I am trying to build ghostscript-9.27rc1 from:

https://github.com/ArtifexSoftware/ghostpdl-downloads/releases/download/9.27rc1/ghostscript-9.27rc1.tar.g

for Alpine Linux, via 'abuild'.  During `make`, I faile with following.  I have disabled options in configure including --with-jbig2dec:

         -Os -fomit-frame-pointer  -Wall -Wstrict-prototypes -Wundef -Wmissing-declarations -Wmissing-prototypes -Wwrite-strings -fno-strict-aliasing -Werror=declaration-after-statement -fno-builtin -fno-common -Werror=return-type -DHAVE_STDINT_H=1 -DHAVE_DIRENT_H=1 -DHAVE_SYS_DIR_H=1 -DHAVE_SYS_TIME_H=1 -DHAVE_SYS_TIMES_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_LIBDL=1 -DGX_COLOR_INDEX_TYPE="unsigned long long" -D__USE_UNIX98=1  -Os -fomit-frame-pointer -g -DHAVE_RESTRICT=1  -fno-strict-aliasing -DHAVE_POPEN_PROTO=1   -I./soobj -I./base -I./devices -Isrc   -o ./soobj/sjbig2.o -c ./base/sjbig2.c
