I just discovered why there is a problem running "ruby extconf.rb" under
MSYS shell. In older ( < 1.7 or 1.8) versions of Ruby, there was problem
with "system" method call, e.g. try:

$ irb
irb(main):001:0> system("gcc -v")
=> false

while 1.8 gives:

ggd@GGD /opt/ruby/bin
$ ruby irb
irb(main):001:0> ENV['PATH']
ENV['PATH']
=>
".;c:/MinGW/bin;C:/MSYS/1.0/BIN;c:/MinGW/BIN;c:/MinGW/LIB;j:/DOS;j:/MERGE;c:/WINDOWS;c:/WINDOWS/COMMAND;."
irb(main):002:0> system("gcc -v")
system("gcc -v")

For building Ruby-GTK2 bindings I had to make one small adjustments in
mkmf-gnome2.rb script, and now the whole environment is correctly
recognized under MSYS shell.

I still have some problems in compiling my own 1.8, but after resolving
it, I'll post my small HOWTO.

Sincerely,
Gour
