Ok this is a weird issue and it's probably cygwin's fault, but I
haven't found any way to fix it so I' thought I would throw it out
here for comment.

I am using git 1.6.0.4 on cygwin. I have a repo where if any file has
changes and git detects as mode 100644 I get this error:
$git diff
      3 [main] git 2744 C:\cygwin\bin\git.exe: *** fatal error - could
not load user32, Win32 error

If I change the mode to 100755 git diff will work fine.
$chmod a+x test.cpp
$git diff

diff --git a/test.cpp b/test.cpp
old mode 100644
new mode 100755
index 7c0dfcd..20987a7
--- a/test.cpp
+++ b/test.cpp

@@ -6,9 +6,11 @@ int main()

 void func()

 }

 void func2()

 }

Anybody have a clue as to why this might occur?  I have seen this in
many of the repo's I use, but it is not repeatable.  I tried making a
test repo but could not reproduce.

Wow, that _is_ weird.  Does your test suite pass?

Forgive my ignorance, but I am not sure how to run the test suite.  I
did a quick google search but didn't find anything.  I am using
cygwin's packaged version of git and am not building it from source,
so maybe the suite is not available.  If I get a chance I will try
building from source.

It is really easy: just make sure that make, gcc, libiconv-dev,
openssl-dev and libcurl-dev are installed (that's it AFAIR), then download
a tarball, e.g.

       http://repo.or.cz/w/git.git?a=snapshot;h=next;sf=tgz

unpack it, cd to it and run "make".  (I would _not_ run configure...)

Hth,
Dscho

Well, after compiling from source the error seems to have disappeared.
Strange. I have seen it disappear before and come back later so I will
watch out for it, but for now it's not an issue.

Just a note, the cygwin names for the packages necessary to compile are
curl-devel
gcc
libiconv
make
openssl-devel
