libgcrypt 1.10.2 compile on AIX POWER

[Frank Lindner]

Hello,

it's been a while and I just tried to compile a new version of GnuPG and needed libraries.
I am having troubles with libgcrypt 1.10.2.

/opt/freeware/bin/bash ../libtool --tag=CC --mode=compile xlclang++ -DHAVE_CONFIG_H -I. -I.. -I../src -I../src -I/opt/freeware/include -qmaxmem=16384 -DSYSV -D_AIX -D_AIX32 -D_AIX41 -D_AIX43 -D_AIX51 -D_AIX52 -D_AIX53 -D_AIX61 -D_AIX71 -D_AIX72 -D_ALL_SOURCE -DFUNCPROTO=15 -O2 -I/opt/freeware/include -fno-delete-null-pointer-checks -Wall -MT mpi-bit.lo -MD -MP -MF .deps/mpi-bit.Tpo -c -o mpi-bit.lo mpi-bit.c

libtool: compile: xlclang++ -DHAVE_CONFIG_H -I. -I.. -I../src -I../src -I/opt/freeware/include -qmaxmem=16384 -DSYSV -D_AIX -D_AIX32 -D_AIX41 -D_AIX43 -D_AIX51 -D_AIX52 -D_AIX53 -D_AIX61 -D_AIX71 -D_AIX72 -D_ALL_SOURCE -DFUNCPROTO=15 -O2 -I/opt/freeware/include -fno-delete-null-pointer-checks -Wall -MT mpi-bit.lo -MD -MP -MF .deps/mpi-bit.Tpo -c mpi-bit.c -DPIC -o .libs/mpi-bit.o

Assembler:

.libs/mpi-bit$1.s: line 48: Error In Syntax

1500-067: (S) asm statement generates errors in assembler output.

make: The error code from the last command is 1.

make: The error code from the last command is 2.

Stop.
error: Bad exit status from /var/tmp/rpm-tmp.XU_aeb (%build)

Currently I have no ideas how to track down this problem any further.
My latest successful build was 1.9.4.

Any ideas?
Is sticking with LTS version (1.8.x) a viable solution?

Kind regards
Frank
