Tom Payerle c42528fac2 fftw: fix include error for 2.x versions (#10039) ... Fixes #7372 Added patch method which renames config.h in the fftw subdir of the source tree. fftw 2.1.5 appears to ship with a copy of this file with all defines commented out. This gets read by the #include directives instead of the version in the build directory with the correct defines. As a result, many C preprocessor macros left undefined, including F77_FUNC_ which causes the bulk of fttwf77.c to be skipped due to an #ifdef, so fftw_reverse_int_array et al not included in library. Fixes #7372 Also fixed some inconsistencies with the handling of quad and long_double in specs between the configure method and the build, check, and install methods.		2019-01-30 21:18:10 -06:00
