Okay:

$ cygcheck -svr | grep gcc
Found: C:\cygwin\bin\gcc.exe
gcc                     3.3.1-3
gcc-g++                 3.3.1-3
gcc-mingw-core          20031020-1
gcc-mingw-g++           20031020-1

The files are updated, but the iconv issue is not resolved. On Html
import, texmacs will crash.

Yes, I have the same errors in the config.log. I have mailed this
behavior to the texmacs developers and hope to get more information.

... searching packages for iconv.h ...

Interestingly, gcc-3.2 has a hit, but *not* gcc-3.3:

usr/include/gnu/gcj/convert/Input_iconv.h
usr/include/gnu/gcj/convert/Output_iconv.h

And gcc-3.2-3.tar.bz2 is four times as big as gcc-3.3.1-3.tar.bz2.

And I can't find the gcc-g++ packet in the repository on my harddisk.

And the page of files for gcc-g++ on cygwin.com is empty:
http://cygwin.com/cgi-bin2/package-cat.cgi?file=gcc-g++/gcc-g++-3.3.1-3&grep=gcc

So I will downgrade to gcc-3.2 and see if I find something...

I changed this in the README and hint file.

export PKG=TeXmacs
export VER=1.0.3.2
export tmp=/tmp
find  $tmp/$PKG-$VER/.inst -name '*.exe' -o -name '*.dll' \
   -o -name '*.bin' | \xargs cygcheck | \
   sed -e '/\.exe/d' -e 's,\\,/,g' | sort -bu | \
   xargs -n1 cygpath -u | xargs cygcheck -f | uniq
cygipc-2.02-1
cygwin-1.5.7-1
libfreetype26-2.1.5-1
libguile12-1.6.4-12
XFree86-bin-4.3.0-8
zlib-1.2.1-1

The other dependencies are caused by scripts, which were not investigated.

Ciao,
Andreas.
