Sign up_h2ph_pre.ph / $Config{cppsymbols} omits gcc-3.4+ cpp "predefined macros" #8305
Comments
From jvdias@redhat.comCreated by jvdias@redhat.comThe gcc cpp "predefined macros" have no definitions in _h2ph_pre.ph, __LONG_MAX__, and __INT_MAX__, and many other '#define's, have NO touch foo.h; cpp -dM foo.h will show all the predefined macros. With gcc-4+ on i386 Fedora Core, many '#define's are "predefined" in cpp: Also, many of these '#define's will cause the current version of So here's a patch against the 5.8.8-RC1 source to merge in the cpp internal <pre> Inline Patch--- perl-5.8.8-RC1/Configure.bz178343 2006-01-08 09:51:03.000000000 -0500

Please consider fixing this issue in the upcoming 5.8.8 / 5.9.3 releases, Thanks & Regards, Perl Info |
From @TuxThe intent of this patch is correct, but the implementation leaves some : Add in any linux cpp "predefined macros": (changes 27363 and 27367) |
