Hello,

While working on latest RubyInstaller release for 1.9.3-p194 our team detected a bigger shared library and import library being generated.

After further inspection, we found this commit:
https://github.com/ruby/ruby/commit/ffdaca1d748804f2b5ca2de612f17cf6c78d351b

Backported r34840 into ruby_1_9_3 branch

The above change added -ggdb to CFLAGS even when was not provided by debugflags configure option.

The following is the comparison of "make" summary with and without the change:

Current trunk:

<pre>
C:\Users\Luis\Projects\oss\ruby\build32>make
        CC = gcc
        LD = ld
        LDSHARED = gcc -shared
        CFLAGS = -O3 -fno-omit-frame-pointer -ggdb -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wunused-variable -Werror=pointer-arith -Werror=write-strings -Werror=declaration-after-statement -Werror=implicit-function-declaration
        XCFLAGS = -include ruby/config.h -include ruby/missing.h -D_FORTIFY_SOURCE=2 -fno-strict-overflow -fvisibility=hidden -DRUBY_EXPORT
        CPPFLAGS = -DFD_SETSIZE=32767 -D_WIN32_WINNT=0x0501   -I. -I.ext/include/i386-mingw32 -I../include -I..
        DLDFLAGS = -Wl,--enable-auto-image-base,--enable-auto-import -Wl,--out-implib=libmsvcrt-ruby200.dll.a msvcrt-ruby200.def -Wl,--stack,0x00200000,--enable-auto-import
        SOLIBS = msvcrt-ruby200.res.o -lshell32 -lws2_32 -limagehlp
</pre>

Reverting r34840:

<pre>
C:\Users\Luis\Projects\oss\ruby\build32>make
        CC = gcc
        LD = ld
        LDSHARED = gcc -shared -s
        CFLAGS = -O3 -fno-omit-frame-pointer -g -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wunused-variable -Werror=pointer-arith -Werror=write-strings -Werror=declaration-after-statement -Werror=implicit-function-declaration
        XCFLAGS = -include ruby/config.h -include ruby/missing.h -D_FORTIFY_SOURCE=2 -fno-strict-overflow -fvisibility=hidden -DRUBY_EXPORT
        CPPFLAGS = -DFD_SETSIZE=32767 -D_WIN32_WINNT=0x0501   -I. -I.ext/include/i386-mingw32 -I../include -I..
        DLDFLAGS = -Wl,--enable-auto-image-base,--enable-auto-import -Wl,--out-implib=libmsvcrt-ruby200.dll.a msvcrt-ruby200.def -Wl,--stack,0x00200000,--enable-auto-import
        SOLIBS = msvcrt-ruby200.res.o -lshell32 -lws2_32 -limagehlp
</pre>

Notice that -g changed into -ggdb instead.

I think debug symbols shouldn't be compiled unless requested and this is a regression.
