I just built FLAC and noticed that the size of flac.exe is noticeably bigger,
so I compared the generated Makefiles before ang after this change.

The difference is: "-g -O2" options were added to CFLAGS.

CFLAGS = -O3 -funroll-loops -Wall -W -Winline -Wall -Wextra -Wstrict-prototypes -Wmissing-prototypes -Waggregate-return -Wcast-align -Wnested-externs -Wshadow -Wundef -Wmissing-declarations -Wunreachable-code  -Wdeclaration-after-statement -D_FORTIFY_SOURCE=2 -msse2 -Wextra

CFLAGS = -O3 -funroll-loops -Wall -W -Winline -g -O2 -Wall -Wextra -Wstrict-prototypes -Wmissing-prototypes -Waggregate-return -Wcast-align -Wnested-externs -Wshadow -Wundef -Wmissing-declarations -Wunreachable-code  -Wdeclaration-after-statement -D_FORTIFY_SOURCE=2 -msse2 -Wextra
