Greetings!  I'm planning a 2.6.11 release in about a week, so if anyone

Skipping this step simplifies things a lot.

Take care,

Which git branch is this?  I will try building on windows then use
gcl to build maxima.

PS. I build from source on windows to build the maxima windows release.

I have just built git head on windows XP with latest mingw gcc 4.8.1.

Just noticed this.  Please test with Version_2_6_11pre, master is not
ready for prime time.

Take care,

gcl builds OK, but I am getting testsuite failures with maxima
(current git head).  I don't get these failures with gcl-2.6.10. Too
late to investigate further tonight.

I have problems with maxima-5.33.0 and Version_2_6_11pre on msys/windows.  Simple test case below.

There are issues with maxima-5.34.0 - released a few days ago - and Lisp implementations which compute floating point infinity by default (GCL, ECL).  See http://sourceforge.net/p/maxima/mailman/message/32778820/ for irrelevant details.  To avoid these I have focused on maxima-5.33.0, which works nicely with gcl-2.6.10.

I am comparing two freshly built gcls, using current mingw/msys 32-bit system under Windows XP SP3.

1. gcl-2.6.10 built from tarball, with configure patched to use system gmp
2. gcl git Version_2_6_11pre of around 12 hours ago

Both gcls are built using "./configure --enable-ansi  --enable-dynsysgmp"

Then build maxima-5.33.0 from tarball, using the two uninstalled gcl
./configure --enable-gcl --with-gcl=<path to>/gcl-xxx/unixport/saved_ansi_gcl.exe
make
make check

Using gcl-2.6.10, all tests pass.  Using Version_2_6_11pre I get a testsuite failure and then a "hang" in rtest11.mac.

I have started digging.  The first reduced testcase is the maxima command "is(%pi>1);"

Using maxima/gcl-2.6.10 the answer is "true"
With maxima/Version_2_6_11pre the answer is "unknown"

I need to put this aside for now, but may get back to it later today.

A further reduced maxima test case is "?sign1(%e);", or at the lisp level (sign1 '$%e)

Using maxima/gcl-2.6.10 the answer is "pos"
With maxima/Version_2_6_11pre the answer is "pnz"
