Hi,

I checked the EPICS site today and found a new cvs version for
download. This is my environment:
==========================================================================
OS: Windows XP SP3

Compiler:
$ gcc -v
Using built-in specs.
Target: mingw32
Configured with: ../gcc-4.3.0/configure
--enable-languages=c,ada,c++,fortran,java,objc,obj-c++
--disable-sjlj-exceptions
 --enable-shared --enable-libgcj --enable-libgomp --with-dwarf2
--disable-win32-registry --enable-libstdcxx-debug --enab
le-concept-checks --enable-version-specific-runtime-libs
--build=mingw32 --with-bugurl=http://www.mingw.org/bugs.shtml -
-prefix=/mingw --with-gmp=/mingw/src/gcc/gmp-mpfr-root
--with-mpfr=/mingw/src/gcc/gmp-mpfr-root --with-libiconv-prefix=/
mingw/src/gcc/libiconv-root
Thread model: win32
gcc version 4.3.0 20080305 (alpha-testing) mingw-20080502 (GCC)

Environment: MSYS

$ echo $EPICS_HOST_ARCH
win32-x86-mingw
==========================================================================

I was told that something error in src/libCom/osi/os/WIN32/osdTime.cpp.
I'm sorry, I can't remember exactly what the error message is, it's
pretty much like
"passing `volatile currentTime' as `this' argument of
`currentTime::startPLL' discards qualifiers"

I "fixed" it by modifying line 88:
static volatile currentTime * pCurrentTime = 0;
to
static currentTime * pCurrentTime = 0;
It compiles OK and runs fine, only that there're so many lines in the
sources and I
can't be sure this would be safe. Can you tell me what is the worst
thing that would
happen?

By the way, about the file
configure/os/CONFIG_SITE.win32-x86-mingw.Common, I really think one
should take care of their $PATH environment themselves, and not all
people would install their
gcc under C:/MinGW/bin. Not only it's not cool, but those lines made
my sh confused and messed
all the $PATH environment and even cannot find "make" itself.

Chen
