Looking through the remaining testsuite failures on i386-pc-solaris2.9, I
noticed two groups that are easily fixable:
FAIL: g++.brendan/crash20.C (test for excess errors)
FAIL: g++.law/code-gen5.C (test for excess errors)
FAIL: g++.law/ctors6.C (test for excess errors)
FAIL: g++.other/headers1.C (test for excess errors)
FAIL: g++.robertl/eb3.C (test for excess errors)
all failed as follows:
libstdc++-v3/include/bits/std_cmath.h: In function `float std::modf(float, float*)':
libstdc++-v3/include/bits/std_cmath.h:356: `::modff' undeclared (first use here)
while modff() is declared in <math.h>, but only inside #ifdef
__EXTENSIONS__. The patch below fixes this by defining CPLUSPLUS_CPP_SPEC
identically to the Solaris 2/SPARC version.
Bootstrapped on i386-pc-solaris2.9 without regressions, removing the
failures above.
Ok for branch and mainline?
