+    Fix build regression with DO_XSI_MATH disabled
+    
+    Commit ea38f4d89 (math: add exception handling functionality) adds a
+    regression so that build configurations that have DO_C99_MATH enabled
+    and DO_XSI_MATH disabled will not link. This commit moves the files with
+    the bessel functions from DO_C99_MATH to DO_XSI_MATH. It looks like they
+    are not even contained in C99.
