Summary: Bootstrap failure: c++locale.cc: invalid conversion
from 'const char*' to 'char*'
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: sk...@iskunk.org
Host: powerpc-ibm-aix4.3.2.0
Target: powerpc-ibm-aix4.3.2.0
Build: powerpc-ibm-aix4.3.2.0
After working around bug #47907, bootstrapping GCC 4.5.2 on this AIX 4.3 system
fails with
ln -s /home/src/gcc-4.5.2/libstdc++-v3/config/locale/generic/c_locale.cc

Sure enough,
% grep strtof /usr/include/*.h
/usr/include/stdlib.h: extern float strtof();
/usr/include/stdlib.h: extern float strtof(char *, char **);
This is the same as bug #26297, except with newer versions of AIX and GCC. I
will attempt adding the const keyword to the strtof() prototype in GCC's copy
of the system stdlib.h.
