Summary: compiling with -fprofile-generate fails on sfnt2fnt
                    due to hidden symbol
           Product: Wine
           Version: 1.1.23
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tools
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I've been attempting to experiment with compiling Wine using profile guided
optimization, however make fails in tools/sfnt2fnt due to a hidden symbol.

GCC version: 4.3  on Ubuntu 9.04

x86_64-linux-gnu-gcc -m32 -Wall -g -O2 -fprofile-generate -o sfnt2fnt
sfnt2fnt.o -L../libs/wine -lwine ../libs/port/libwine_port.a  -lfreetype -lz
-Wl,--rpath,$ORIGIN/../libs/wine
/usr/bin/ld: sfnt2fnt: hidden symbol `__gcov_merge_add' in
/usr/lib/gcc/x86_64-linux-gnu/4.3.3/32/libgcov.a(_gcov_merge_add.o) is
referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output

If I try hacking the makefile to add the -fno-profile-generate flag after that
one, I get this error:

This is strange as compiling without -fprofile-generate works fine.
