I have a significant amount of Windoze code that I'm porting to Linux which uses 16 bit wide characters extensively. -fshort-wchar has served me well so far, but now I'd like to rebuild glibc for 16 bit wide character support. I thought it would be fairly simple to build a custom version of gcc/glibc, but I haven't had any success. Unless I specify -fshort-wchar a program compiled with my custom gcc still shows sizeof(wchar_t) to be 4 bytes and glibc is still using 4 byte wchars.
Since I'm building a cross compiler for the ARM I picked gcc 3.4.1 and glibc 2.3.3 since those versions build for the ARM using crosstool-0.28 rc37 without any fuss. Currently I'm building an x86 compiler just to simply things.
In the gcc source tree I changed WCHAR_TYPE and WCHAR_TYPE_SIZE in .../gcc/config/i386/linux.h and .../gcc/config/i386/linux-aout.h to "short unsigned int", and WCHAR_TYPE_SIZE to 16 respectively.
In the glibc source tree I changed __WCHAR_MIN and __WCHAR_MAX in
.../sysdeps/unix/sysv/linux/i386/bits/wchar.h to -32786 and 32767 respectively.
I've verified that those are the headers that are being references when gcc is built.
I'm passing the following to the crosstool scripts: TARGET=i686-unknown-linux-gnu TARGET_CFLAGS="-O -fshort-wchar -g"
I've also tried without the -fshort-wchar flag in TARGET_CFLAGS without success.
What am I missing? Any help would be most appreciated!
