Summary: no predefined macros __amd64, __amd64__, __x86_64
__x86_64__ in prepocessor
Product: gcc
Version: 4.4.5
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: jan.raub...@gmx.de
Matlab and probably other software uses the predefined macros to check for the
current platform to enable long pointer or not. I have found that the macros
above are no more in gfortran 4.4 and higher. The only way to check for the
right platform is the __LP64__ macro which seems not to be used on other
compiles like sunf90. It takes me some hours to find why a Matlab mex file
crashes immediately after calling. Whith gcc these macros are available, why
not whith gfortran?
