Bug ID: 57768 Summary: Assumption of a case-insensitive filesystem on Darwin is incorrect Product: gcc Version: 4.7.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: preprocessor Assignee: unassigned at gcc dot gnu.org Reporter: a...@alex-smith.me.uk Revision 175762 changed filename_cmp in libiberty to assume a case-insensitive filesystem on Darwin. While it's true that this is the default, you can still create case-sensitive HFS+ volumes. This is causing issues for me building Haiku using a cross-compiler from my OS X host (10.8.4) - Haiku requires building off a case-sensitive volume, but because filename_cmp is performing comparisons case-insensitively I'm getting various build issues. For example, there is a header String.h for the BeOS API BString class, which includes the C library string.h. The preprocessor is just matching the second header's name against the first header which it has already seen using its cache, so the second one doesn't get included.
