Hi, Ludovic,

mem_iconveh () returns ENOSYS, in "striconveh.c" line 1139.
This is out of "#if HAVE_ICONV" but in "#else".

Maybe configure did not find "iconv.h".

I built guile again with configure options
  --with-libiconv-prefix=
  --with-libunistring-prefix=
  --with-libltdl-prefix=
  --with-libgmp-prefix=
  --with-libintl-prefix=
and set all the include pathes to CPATH environment for gcc.
With these, make passed without any problem.

I downloaded the latest snapshot "guile-2.0.5.100-0f6dd" and tryed making.
The result is:
(1) with -m64
make passed, and "make check " also passed except for 1 FAIL:
FAIL: time.test: strftime: C99 %z format: EST+5

(2) with -m32
Failed with Segmentation Fault as:
make[3]: Entering directory `/tmp/guile-2.0.5.100-0f6dd'
Testing /tmp/guile-2.0.5.100-0f6dd/meta/guile ...
with GUILE_LOAD_PATH=/tmp/guile-2.0.5.100-0f6dd/test-suite
/bin/bash: line 5: 14661 Segmentation Fault      (core dumped) CHARSETALIASDIR="/tmp/guile-2.0.5.100-0f6dd/lib" ${dir}$tst
FAIL: check-guile

This is less inportant because it occurs in "make check" phase, not in "make" phase.
But if you do not mind helping me, I'll try to find what causes this.
Backtrace is attached as "backtrace.txt".
